ABSTRACT: The format method of structural making plans and layout calls for now not most effective imagination and
conceptual thinking however moreover sound knowledge of technology of structural engineering except the statistics of
Realistic", which incorporates brand new design codes bye legal tips sponsored up with the resource of sufficient enjoy,
instinct and judgments.". The cause of standards is to make certain and decorate the protection, preserving cautious stability
among economy and safety. In the present look at multistory residential constructing in good fortune now India is designed
(slab, beam, column, floor, wall, footings) the use of AutoCAD, E-tab, software. Find the stress assessment in slab, shear
pressure for beam, lateral load, axial load, longitudinal load, seismic or wind and vicinity reinforcement for the column and
stair case, boost in those one-of-a-kind force are acting and evaluation and layout depending upon the reaction and height of
the foundation degree rely upon the website online safe bearing capability of the soil "because of balance purpose designed
the keeping wall in this task.. In order to layout them ,it's far important to first achieve the plan of the specific building that is ,
positioning of specific room ( Drawing room, bed room, kitchen, wash room, balcony , stair case and raise and many others. )
Such that they serve their respective motive and additionally suiting to the requirement and comfort of the inhabitant."Such
that they serve their respective reason and moreover suiting to the requirement and comfort of the inhabitant.". There
through depending at the suitability, plan format of beam and the placement of column are constant. Thereafter, the loads are
calculated particularly the useless loads, which rely upon the unit weight of the substances used concrete and metal and brick
and stay loads. Footings are design primarily based at the safe bearing capacity of soil. For designing of column and beam, It is
important to recognize the moment they may be subjected to , one-manner, two- way slab the stop condition and the loading.
From the slab, the hundreds are transferred to the them. Thereafter, the hundreds (specially shear) from the beam are taken
through the columns. Finally, the phase has to be checked and analyze for the whole 4 aspect with regard to energy and
provider capability.
Keyword: AutoCAD, STAAD Pro, E-tab, beam, column, wall, slabs, footing, structural designing.
INTRODUCTION
ETAB are commonly makes use of for analysis and layout for building machine. ETAB function are contain powerful graphical
interface coupled with unequalled modeling, analytical, and layout procedures, all incorporated the use of a commonplace
database. It is short and really smooth for shape. It can take care of the most important and complex constructing fashions.
ETAB (Extended 3 dimensional evaluation of building system) is software which is included with all of the fundamental
evaluation engines this is static, dynamic, linear and non-linear, etc. And specifically this software program is used to
investigate and design the building .This program has been very well examined and utilized in the usage of this system.
However, the complete person accepts and understands that no guarantee is expressed via the builders or the vendors at the
accuracy or the reliability of the program. This software is a totally beneficial tool for the layout test of concrete systems. ETAB
is the present time leading design software in the market. Many design company’s use this software for their project design
purpose. So, this paper deals with the mainly analysis of the results obtained from the analysis of a multistory building
structure when analysis and design and using ETAB software.
Structural reaction to earthquake rely on dynamic symptoms of the structures and intensity, period and frequency are existing
ground motion. "Structural evaluation method strength of mind of the overall shape and all of the precise dimensions of a
specific form in order that it carry out the characteristic for which it's far creates and" will protection face up to the impacts in
an effort to act on it during its beneficial lifestyles. The effective layout and creation of a earthquake resistant structures have
extremely good important all around the global. This challenge gift evaluation and layout if multistory residential constructing
as consistent with INDIAN CODES- IS 1893-part2:2002, IS 456:2000.And use national building codes. The analysis is done with
the aid of thinking about seismic zones and conduct is classified with the aid of taking type-III Soil situation. In our mission
we're thinking about a plan underneath quarter-III .Seismic depth is intense and zone issue is 0.Sixteen at Luck now. Can

layout of steel and urban frame, composite beam and column, steel joints, and concrete and masonry shear wall, complete and
customizable reports are to be had for all evaluation and design output, and schematic production drawings of framing plans,
schedules, details, and cross-section can be generated for concrete and steel structure ETAB. ETAB contain every element of
the engineering design system. The introduction of fashions has in no way been clean – The AUTOCAD drawings may be
transformed directly into ETAB model & can effortlessly evaluation and layout of constructing

RESULT ANALYSIS
Load Patterns:
Dead loads:
I. Dead load is the self weight of the building components such as beams, columns, slabs, flooring, roofing, and brick
masonry.
II. Dead load is calculated using the unit weight of the materials such as concrete, brick masonry, flooring etc multiplied
by their volume.
III. In ETABS automatically taken care by the software i.e. Inbuilt.
IV. In this project analysis and design of dead load use IS: 875 (PART 1)-1987 code.
Live loads:
I. Live loads or Imposed loads is the load which is not static and thus varied throughout the service life of the building.
II. In this project analysis and design of live loads use IS: 875 (PART 2)-1987 code.
III. Residential buildings: some specific value use in this project for analysis and design.
S.No Dwelling houses: (UDL) KN/m2 ( C.L) KN
1 All room and kitchen 2 1.8
2 Toilet and bath rooms 2 ….
3 Corridors, passages, stair-cases including
tire escapes and store rooms
3 4.5
4 Balconies 3 1.5 per meter
Wind load:
I. Buildings of height up to 10 meter are subjected to constant wind loads and above 10 meter subjected to varying wind
loads.
II. In this project analysis and design of wind load use IS 875: 2015 code.
Parameters considered for determining the wind loads:
1. Basic wind speed (Vb): 47 m/s (Luck now Zone).
2. Building category-2.
3. Building class-B.
4. Risk coefficient ( K1): 1.0
5. Terrain coefficient (K2): ( 1.02-1.05 ) for building between 15 to 20 meter height.
6. Topography coefficient (K3) = 1.
7. Wind velocity ( VZ) = (Vb x K1x K2 x K3) m/s .
8. Wind Intensity (PZ) = ( .6VZ
2) N/m2 .
9. Wind loads ( F ) = ( Cpe – Cpi ) APz ( N ).
10. Opening: ( 5-20%)/ wall.
11. External pressure coefficient (Cpe) = .7 for surface A of the roof.
12. Internal pressure coefficient ( Cpi ) = ± .5 for ( 5-20%) opening.

13. Formula for varying wind velocity: - Vz/Vb=(Z/Zo)α ( α =.9 and category 2).
Load combination:-
It should be remembered that for structures that have lateral force resisting elements in two orthogonal directions only the
earthquake force or wind force is applied only along one direction X or Y at a time and the including in analyzed.
Various loads combinations are as follows:
1. 1.5 ( DL + LL )
2. 1.5 ( DL ± EQ In X- direction )
3. 1.5 ( DL ± EQ In Y- direction )
4. 1.2 ( DL + LL ± In X- direction )
5. 1.2 ( DL + LL ± In Y- direction )
To check overturning:
1. .9 DL ± 1.5 EQ In X- direction )
2 .9 DL ± 1.5 EQ In Y- direction

Conclusions:-
1. In this task are used constructing through legal guidelines, according to NATIONAL BUILDING CODE 2005.
2. This evaluation and layout is supplying ok electricity, serviceability and durability except financial system.

3. In structure are acting lateral force in x and y direction in all story of building within permissible limit. And story
drift, dead load ,live load (induced shear force, bending moment) and axial force variation are in picture diagram
also within permissible limit.
4. After analysis and design are check different section of beam and column, base reaction, story forces, max. / avg.
drifts and model period and frequencies and also check beam & column overwrites , slab punching shear design,
finite element based in concrete slab design come within permissible limit and safe structure and giving on
warning & no error messaging completion of analysis and design.
5. So overall above conclusion our building structure are come in economical condition and safe in all way imp
