INTRODUCTION
INTRODUCTION
AIM
Our main aim to complete a Multi-storey building is to ensure that the structure is safe
against all possible loading conditions and to full fill the function for which they have built.

Safety requirements must be met so that the structure is able to serve its purpose with the
maintain cost.
Detailed planning of the structure usually comes from several studies made by town
planners, investors, users, architects and other engineers. On that, a structural engineer has the
main influence on the overall structural design and an architect is involved in aesthetic details.
For the design of the structure, the dead load, live loads, seismic and wind load are
considered. The analysis and design for the structure done by using a software package STAAD
PRO.
In this project multistoried construction, we have adopted limit state method of
analysis and design the structure. The design is in confirmation with IS456-2000.the analysis of
one frame is worked out manually and simultaneously it has been checked using STAAD PRO.
Therefore an attempt has been made to present the multistoried building for residential
purpose in the busy city of Hyderabad.The complex consisting of five storeys The structure is
design based on the theory of LIMITSTATE METHOD which provides adequate
strength,serviceability and durability besides economy

LITERATURE SURVEY
LITERATURE SURVEY
Major advances in both design and new material assisted roman architecture. Design
was enhanced architectural developments in the construction of arches and roof domes. Arches
improved the efficiency and capability of bridges and aqueducts (fewer supports columns were
needed to support the structure), while domed roofs not only permitted the building of larger
open areas undercover, but also lent the exterior an impressive.

The social unit that lives in a house is known as a household. Most commonly, a household is
family unit of a same kind, though households can be other social groups, such as single person,
or groups of unrelated individuals. Settled agrarian and industrial societies are composed of
household units living permanently in housing of various types, according to a variety of farms
of lands tenure. English-speaking people generally call any building there routinely occupy
“home”. Many people leave their houses during the day for work and recreation, and return to
them to sleep or for other activities.

CHAPTER – 3
ARCHITECTURE
ARCHITECTURE
Architecture is the art and science of designing buildings and structures. A wider definition
would include within its scope also the design of the total built environment, from the macro
level of creating furniture. In the field of building architecture, the skill demanded of an architect
range from the more complex, such as for a hospital or stadium, to the apparently simpler, such
as planning residential houses. Many architectural works may be seen also as cultural and
political symbols, and /or work of art. The role of architect though changing, has been central to
the successful design and implementation of pleasing built environments in which people live.
Scope: Architectural is an interdisciplinary field, drawing upon mathematics, science, art
technology, social sciences, politics, history and philosophy. Vitrifies states: “architecture is a
science, arising out of many other sciences, and adorned with much and varied learning: by the
help of which is judgment is formed of those works which are result of other arts”.

Most modern-day definition of “good buildings” recognize that because architecture
does not exist in a vacuum, architectural form cannot be merely a completion of historical
precedent, fictional necessities ; and socially aware concerns, but most also be a trance dents
synthesis of all of the former and a creation of worth in and of itself. As Nunziarodanini stated,
“through its aesthetic dimension architecture goes beyond the functional aspects that it has in
common with other human sciences…through its own particular way of expressing values,
architecture can stimulate and influence social life without presuming that, in and of itself, it will
promote social development. To restrict the meaning of formalism to art for art’s sake is not only
reactionary; it can be a purposeless quest for perfection or originality which degrades fro, into a
mere instrumentally”
The term can be used to connect the implied architecture of abstract things such as music or
mathematics the apparent architecture of natural things, such as geological formations or the
structure of natural things such as geological formations or the structure of natural things such as
geological formation or the structure of biological cells, or explicitly planned architectures of
human made things such as software, computers, enterprises, and databases, in addition to
buildings. In every usages an architecture may be seen as subjective mapping fro, a human
perspective (that of the user in the case of abstract or physical artifacts) to the elements or
components.
Architecture is both the process and product of planning designing and constructing
space the reflects functional, social and aesthetic considerations. It requires the manipulation and
coordination of material. Technology, light and shadow.Architecture also encompassed the
pragmatic aspects of realizing designed spaces, such as project planning, cost estimating and
construction administration.
Architectural works are often perceived as cultural and political symbols and as work of
art. Historical civilization is often identified with their surviving architectural achievements.
Brunelleschi, in the building of the dome of Florence cathedral, not only transformed the
cathedral and the city of Florence, but also the role and status of the architecture.
With the consolidation of knowledge in scientific such as engineering and the rise of
new building material and technology; the architect began to lose ground on the technical aspect
of building. Therefore he concerned playing field that of aesthetics.
There was the rise of the “gentlemen architect” who usually dealt with wealthy clients
and concentrated predominantly on visual qualities derived usually from historical prototypes. In

the 19th
century, Cole des Beaux Arts in France,the training was toward producing quick sketch
schemes involving beautiful drawings without much emphasis on context. The rise of profession
of industrial design is usually placed here. Following this lead, the Bauhaus school, founded in
Germany in 1919, consciously rejected history and looked at architecture as synthesis of art craft
and technology.
Architects such as Miens van Dee roe worked to reject the virtually all that had come
before, trading handcrafted details and sentimental historic forms for a machine driven
architectural geometry made possible by the Industrial Revolution. They felt that architecture
was not a personal philosophical or aesthetic pursuit by individual rather it had to consider
everyday needs of people and use technology to give a livable environment. That design
Methodology Movement involving people such as chirrs Jones, Christopher Alexander started
for more people-oriented designs.
Extensive studies on areas such as behavioral, environmental, and social science were
done started informing the design process. as many other concerns began to be recognized,
complexity of buildings began to increase in terms of aspect to be recognized, and complexity of
buildings began to increase in terms of aspect such as services, architecture started becoming
more multi-disciplinary than ever. While the notion that structural and aesthetic consideration
should be entirely subject to functionality, which met with both popularity an skepticism, it had
the effect of introducing the concept of “function” in the place of Vitruvius “utility”. “Function”
came to be seen as encompassing all criteria of the use, perception and enjoyment of a building,
not only practical but alsoaesthetic, psychological and cultural.
“Now-a-day’s Architecture required a team of professionals in its making”.
An architect is being one among the many and sometimes the leader. This I the state of the
professional today, however, individually o still cherished and sought the design of buildings
seems as cultural symbols – the museum of fine arts centre has become a showcase for new
experiments in style, tomorrow may be something’s else.
In the late 20th
century, a new concept was added to those include in the compass of both
structure and function, the consideration of sustainability. To satisfy the contemporary ethos a
building should be a constructed in a materials, its impact upon the natural and built environment
of its surroundings area and the demands that it makes upon non-sustainable power sources for
the heating, cooling water and waste management and lighting. When modern architecture was
first practiced, it was an avant-garde movement with moral, philosophical, and aesthetic

underpinnings. Modernist architects sought to reduce buildings to a pure form, removing
historical references in favors of purely fictional structures.
The column arches and gargoyles of classical architecture were dubbed unnecessary.
Buildings that flaunted their construction exposing steel beams and concrete surfaces instead of
hiding them behind traditional forms were beams and concrete surfaces instead of hiding them
behind traditional forms were seen as beautiful in their own right. Architecture first evolved out
of the dynamics between needs (shelter, security, worship etc.,) and means (available building
material and attendant skills). As human culture evolved and knowledge began to be formalized
through oral tradition and practices, architectures became a craft.

sTRUCTURAL ANALYSIS

The procedure of structural analysis is simple in concept but complex. In detail. It
involves the analysis of a proposed structure to show that its resistance or strength will meet or
exceed a reasonable expectation. This expectation is usually expressed by a specified load or
the demand and an acceptable margined of safety that constitutes a performance goal for a
structure. The performance goals structural design is multifaceted. Foremost, a structure must
perform its intended function safely over its useful life.
The concept of useful life implies consideration of durability and established the basis for
considering the cumulative exposure to time varying risks (i.e. corrosive environments, that
performance is inextricably linked to cost, owners, builders, and designer must considers
economic limit to the primary goal of safety and durability.
In the view of the above discussion, structural designer may appear to have little control
over the fundamental goals of structural design except to comply with or exceed the minimum
limits established by law. While this is generally true, a designer can still do much to optimize
the design through alternative means and methods that can for more efficient analysis techniques,
creative design detailing, and the use of innovative construction materials and methods. In
summary the goal of structural design are defined by law and reflect the collective interpretation
of general public welfare by those involved in the development and local adoption of building
could.
It is advantageous when kinematic indeterminacy< static indeterminacy. Alex Bendex first
formulated this procedure in 1914 based on the applications of compatibility and equilibrium of
compatibility and equilibrium conditions.
This method derives its name from the facts that supports and displacements are explicitly
computed. Set up simultaneous equation is formed from the solution of these parameters and the
join moment in each or computed from these values.

STRUCTURAL DESIGN

Design of Multistoried Residential Building
General:
A structure can be defined as a body, which can resist the applied loads without
appreciable deformations. Civil engineering structures are created to serve soma specific
like, Human habitation, transportation, bridges, storage etc. in safe and economical way.
A structure is assembling of individual elements like pinned elements (truss elements),
beam elements, column, shear wall slab able or arch. Structural engineering is concerned
with the planning, designing and the construction of structures.
Structural analysis involves the determination of the forces and displacements of the
structures or components of a structure that make up the structural system.
The main object of reinforced concrete design is to achieve a structure that will result in
a safe economical solution.
The objectives of the design are,
I.Slab Design.

II.Beam Design.
III.column Design.
IV.Foundation Design.
Foundation Design
Foundations are the structure elements that transfer loads from buildings or individual
column to earth this loads are to be properly transmitted foundations must be designed to
prevent excessive settlement are rotation to minimize differential settlements and to provide
adequate safety isolated footings for the multistoried buildings. These may be square rectangle
or circular in plan that the choice of types of foundation to be used in a given situation depends
on a number of factors.
1. Bearing capacity of soil.
2. Types of structure.
3. Types of loads.
4. Permissible differential settlements.
5. Economy.
Column Design

A coloumn may be defines as an element used primarily to support axial compressive
loads and with a height of at least three times its lateral dimensions. The strength of column
depends up on the strength of material, shape and size of cross section length and degree of
proportional and dedicational restrains at the ends.
1. Shape of cross section.
2. Slenderness ratio (A=L+D)
3. Type of loading, land.
4. Pattern of lateral reinforcement.
The ration of effective coloumn length to least lateral dimension is released to as
slenderness ratio.
Beam Design
A reinforced concrete beam should be able to resist tensile, compressive and shear stress
induced in it by loads on the beam.
There are three types of reinforced concrete beams.
1. Single reinforced beams.
2. Double reinforced concrete.
3. Flanged beams
Slab Design
A slab is a thin flexural member used in floor and roofs of structure to carry loads,, which
are usually supported by wall or beams along its edges. Slabs are plate elements forming
floor and roofs of buildings carrying distributed loads primarily by flexure.
One- Way Slab

One-way slabs are those in which the length is more than twice the breadth it can be simply
supported beam or continuous beam.
Two-Way Slab
When the slab is supported on four edges and aspect ratio(Ly/Lx)<2 the slabs are
designed as two way slabs. When slabs are supported to four sides two wayspanning action
occurs.
In two way slabs when loaded it bends in surface along both short and long span
direction causing bending moments in both direction.
Corners held down and bending moments coefficient obtained from table 26 of IS 456-
2000. In slabs M25 grade concrete and Fe415 grade steel is used.

Loads for Residential Buildings

Loads are primary consideration in any buildings design because they define the nature
and magnitude of hazards or external forces that a building must resist to provide reasonable
performance (i.e.; safety and serviceability) throughout the structure’s useful life.
The anticipated loads are influenced by a building’s intended use (occupancy and
function), configuration (shape and size) and location (climate and site conditions).
Ultimately, the type and magnitude of the design loads affect critical decisions such has the
material selection, construction details, and architectural configuration.
Thus to optimize the value (i.e. performance versus economy) of the finished product, it
is essential to apply design loads realistically. While the building consider in this guide are
primary single-family detached and attached dwellings, the principles and concepts related
to building loads also apply to other similar types of construction, such as low-rise
apartment’s buildings.
In general, the design loads recommended in this guide are based on:
1. Dead load.
2. Live load.
3. Imposed loads.
Dead Loads
This is the permanent of the stationary load like self weight of the structural elements.
This include the following
a) Self-weight
b) Weight of the finished structure part.
c) Weight of partition walls etc.
Dead loads are based upon the unit weights of elements, which are established taking in
account materials specified for construction, given IS 1911-1967

Dead loads consists of the permanent construction material loads compressing the roof,
floor, wall, and foundation system, including claddings finishes and fixed equipment. Dead
load is the total load of all of the components of the building that generally do not change
over time, such as the steel columns, concrete floors, bricks, roofing material etc.
Live loads
These loads are not permanent or moving loads. The following loads includes in this
type of loading: imposed loads(fixed) weight of the fixed seating in auditoriums, fixed
machinery, partition walls these loads through fixed in positions cannot be relieved upon to
act permanently throughout the life of the structure.
Imposed loads (not fixed) these loads change either in magnitude or position very often
such as the traffic loads, weight of the furniture etc.
Live loads are produced by the use occupancy of the building. Loads include those from
human occupants, furnishings, no fixed equipment, storage, and constriction and
maintenance activities. As required to adequately define the loading condition, loads are
presented in terms of uniform are loads, concentrated loads, and uniform line loads.
Imposed loads:
Loads produced by intended use occupancy of a building including the weight movable
portions distributed concentrated loads and loads that vibration and impact called imposed
loads estimated by IS 456-2000.

ANALYSIS BY USING
STAAD PRO.

The building frame has five storeys. Concrete mix design of grade M25 and HYSD Fe415 for all
the member of the structure.
Total dead load on slab=3.8 KN/M2
Total live
on slab =2KN/M2

The structural plan has drawn using AUTOCAD, which later imported to STAAD. Pro for
analysis is presented.
The STAAD program for the multi storey building is as follow.

FOOTINGS
DESIGN OF FOOTING

Design of footing under column ’K’
Factored load on column =1090.1KN
Size of column -230x450mm
SBC of soil (Hard Morram) is 300 per code for working load
Self weight of footing =10% of =
=0.1x1090.1=09.01KN
Area footing =
=[1090.1=109.01]/300=4m ²
Provide a square footing of size =1.5m x 2.7m
Net upward pressure intensity =1090.1/[1.5 x2.7] = 269.14 KN/m ²
Design of flexure:
Critical section occurs at the face of column
L= (2.7-0.45) / 2= 1.125
= = (269.14 x 1.5 x 1.125 x 1.125) = 510.92 KN M
Lu = (1.5-0.23) / 2 = 0.635m
= (1.5 x 269.14 x 0.635 x 0.635) / 2 = 81.39KN.M
Depth of footing:
D= [510.95 x 10^6/2.3 x 1000] ^0.5=430mm

Increase depth to account for shear
Taking d = 700mm
Slope height = 300
Flat height = 300mm
Check for One –Way shear
Critical shear force occurs at a distance of `d’ from face of the column
X = [2.7 -4.45]/2-0.7 = 0.425
Shear force V = 0.425 x 1.5 x 269.4 = 257.6 KN
Nominal shear stress
= 257600/ [1500 x 408] =0.42 N/mm²
For 0.46% of steel = from IS456:2000 table- 19
Permissible shear stress ( ) = K where K=1
= 1 x 0.47 = 0.47N/mm²
Footing is safe in shear
Check for Two- way shear
Critical shear occurs at a distance of d/2 from face of the column
Nominal shear stress =
Shear force = 1090.1-[1.15 x 0.93 x 269.1] = 802.29 KN

= 802290/ [2(1.15=0.93) x 1000 x 530] = 0.36 N/mm^2
Permissible shear stress τc

Providing Dog-legged stair case
General arrangements
Width of landing =250mm

Height of rise =150mm
Width of landing =2.00m
Width of flight =105m
Height of flight =125mm
No. of rises in each flight = (1500/150)=10
No. of treads in each flight = 10-19 no’
Load Calculations
D.L of waist slab = 1066x 1x 1.025 x 25 = 3.625
Steps = 0.5 x 0.78 x 0.15 x 25 = 1.837
Floor finish load =1.000
Live load =3.000
Total load = 9.462 KN/m²
Bending Moment Calculations:
Factored load = 9.75 x 1.5 = 14.9 KN/m²
Effective length = 4.3m
Moment at the ends
B.M= = = 21.86KN/m²
Moment at the center

B.M = = =10.93 KN/m²
Check for depth:
√M/2.76 x 1000
=√21.86 x 10 / 2.76 x 1000 =88.99 125mm safe
Check for depth from deflection consideration
I/d = 32
Æ d = 1000/ 32 = 21.25 125m
Area of steel:
Astend = 22.34 x 10
0.87 x 425 x (125 – 0.42 x 0.48 x 125)
= 531.58 mm²
Using 10mm ø bar

CONCLUSIONS
Staad Pro software has become more and more critical in the analysis of engineering and
scientific problems. Much of the reason for this change from manual methods has been the
advancement of computer techniques development by the research community and in
particular universities.
As technology and engineering adoptions are advertising new methodology of
interlinking and completing the industries via computer applications are created with a
similar improvement in hardware capacities. This is turn facilities the implementations of
more effective and professional engineering software. As the applications adventure in
functionality, one can hope that they will be more affordable to promote their widespread
usage amongst civil engineering at a global scale.

Taking into account the technological advance, this project has been dealt with
using the latest design software.
