Abstract - The principle objective of this project is to Plan,
analyse and design a multi-storeyed building [B + G + 15(3
dimensional frame)] using ETABS. The design involves
analysing the whole structure by ETABS. The design methods
used in ETABS analysis are Limit State Design conforming to
Indian Standard Code of Practice. ETABS features a state-of-
the-art user interface, visualization tools, powerful analysis
and design engines with advanced finite elementand dynamic
analysis capabilities. From model generation, analysis and
design to visualization and result verification, ETABS is the
professional’s choice. Initially it started with the analysis of
simple 2 dimensional frames and manually checked the
accuracy of the software with the results. Theresultsproved to
be very accurate for all possible load combinations [dead, live,
wind and seismic loads].
Key Words: Gravity load, High rise, Etabs, Design.
1. INTRODUCTION
A building is a permanent or temporary structure enclosed
within exterior walls and a roof or consisting of a R.C. frame
structure and including all attached apparatus, equipment,
and fixtures that cannot be removed without cutting into
ceiling, floors, or walls. Buildings come in a variety of sizes,
shapes and functions, and have been adapted throughout
history for a wide number of factors,frombuildingmaterials
available, to weather conditions, to land prices, ground
conditions, specific uses and aesthetic reasons. Multi storey
buildings aim to increase the floor area of the building
without increasing the area of the land the building is built
on, hence saving land and, in most cases, money (depending
on material used and land prices in the area). The design
process of multi stored building requires not only
imagination and conceptual thinking but also sound
knowledge of science of structural engineering besides the
knowledge of practical aspects, such as recent design codes,
bye laws, backed up by ample experience, intuition and
judgment. The purpose of standards is to ensure and
enhance the safety, keeping careful balance between
economy and safety.
2. LOADS AND LOAD COMBINATIONS
Loads and properties of materials constitute the basic
parameters affecting the design of a RCC Structure. Both of
them are basically of varying nature. The correct assessment
of loads/forces on a structure is a very important step and
serviceable design of structure.
2.1 TYPES OF LOADS
The loads are broadly classified as vertical loads, horizontal
loads, and longitudinal loads. The vertical loads consist of
dead load, live load, impact load. The horizontal loads
comprises of wind load and earth quake load.
3. CODE-BASED PROCEDURE FOR SEISMIC
ANALYSIS
Main features of seismic method of analysis based on
Indian standard 1893(Part 1):2002 are described as
follows

3. EQUIVALENT STATIC ANALYSIS
All design against seismic loads must consider the dynamic
nature of the load. However, for simple regular structures,
analysis by equivalent linear static methods is often
sufficient. This is permitted in most codes of practise for
regular, low-to medium-rise buildings. It begins with an
estimation of base shear load and its distribution on each
story calculated by using formulas given in the code.
Equivalent static analysis can therefore work well for low to
medium-rise buildings without significant coupled lateral-
torsional effects, are much less suitable for the method, and
require more complex methods to be used in these
circumstances.

4. OBJECTIVES
 To study the existing literatures for the preparation
of plan, analysis, design and reinforcementdetailing
of a regular structure.
 To prepare the model using ETABS and check the
adequacy of the structural component size of the
regular framed structures.
 To obtain the structural parameters of the regular
framed structure such as lateral forces, story drift,
floor displacements, moments and shear force.
 To design, detail and to provide the adequate
member sizes, reinforcementandconnectiondetails
so that to enable the structure to withstand safely
against the calculated loads.

The structure is analysed and designed for live load and
dead load consisting of self-weight of beams, columns and
slabs.
5. BUILDING PLANNING
It is very importanttohaveideaaboutplanningdependingon
the functions for which the building is planned. Initially the
planningbeginswithsiteinvestigationsandconsiderationsof
NBC. Later the drawings are prepared in AutoCAD 2014.
Considering all the amenities andspacesanditsarchitectural
plan is prepared with a basic elevation. The drawings are as
follows.

5. STRUCTURAL ANALYSIS AND DESIGINING RESULTS
From the below fig. 8, it is shown that the multi storied
frame structure has been designed for 15 stories. The slabs
have been modelled on top of the beams using end to end
beam connectivity. The beams dimensions being 230mm x
750mm & 230 x 600mm have been modelled throughout the
structure. The column dimensions havebeensplicedsuitably
based on the requirementofthedesignconsiderationsandso
in as to reduce the load from the structure. The bottom ends
of the columns have been assigned as fixed such that the end
describes it to be fixed to the footing.
