Abstract— The layout method of structural planning and

layout requires no longer simplest creativeness and

conceptual wondering but additionally sound understanding

of science of structural engineering besides the information

of Practical", which includes latest design codes bye legal

guidelines subsidized up with the aid of sufficient experience,

intuition and judgments.". The purpose of standards is to

ensure and enhance the safety, keeping careful balance

between economy and safety. In the present study multistory

residential building in luck now India is designed (slab, beam,

column, floor, wall, footings) using AutoCAD, E-tab,

software. Find the stress analysis in slab, shear force for

beam, lateral load, axial load, longitudinal load, seismic or

wind and area reinforcement for the column and stair case,

lift in these different force are acting and analysis and design,

depending upon the reaction and height of the foundation

level depend upon the site safe bearing capacity of the soil

"because of balance motive designed the preserving wall on

this task.. In order to design them ,it is important to first

obtain the plan of the particular building that is , positioning

of particular room ( Drawing room, bed room, kitchen, wash

room, balcony , stair case and lift etc. ) Such that they serve

their respective motive and additionally suiting to the

requirement and comfort of the inhabitant."Such that they

serve their respective motive and additionally suiting to the

requirement and comfort of the inhabitant.” There by

depending on the suitability, plan layout of beam and the

position of column are fixed. Thereafter, the loads are

calculated namely the dead loads, which depend on the unit

weight of the materials used concrete and steel and brick and

live loads. Footings are design based on the safe bearing

capacity of soil. For designing of column and beam, It is

necessary to know the moment they are subjected to, one-

way, two- way slab the end condition and the loading. From

the slab, the loads are transferred to the them. Thereafter, the

loads (mainly shear) from the beam are taken by the columns.

Finally, the section must be checked and analyze for the entire

four component with regard to strength and service ability.

I. INTRODUCTION

ETAB are generally uses for analysis and design for building

system. ETAB feature are contain powerful graphical

interface coupled with unmatched modeling, analytical, and

design procedures, all integrated using a common database. It

is quick and very easy for structure. It can handle the largest

and complex building models. ETAB (Extended three

dimensional analysis of building system) is software which is

incorporated with all the major analysis engines that is static,

dynamic, linear and non-linear, etc. and especially this

software is used to analyze and design the building.This

program has been thoroughly tested and used in using the

program. However, the entire user accepts and understands

that no warranty is expressed by the developers or the

distributors on the accuracy or the reliability of the program.

This program is a very useful tool for the design check of

concrete structures.

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 response to earthquake depend on

dynamic symptoms of the structures and intensity, duration

and frequency are existing ground motion. "Structural

analysis method willpower of the general form and all of the

particular dimensions of a particular shape so that it carry out

the function for which it is creates and" will safety withstand

the influences which will act on it throughout its useful

life.The effective design and construction of a earthquake

resistant structures have great important all over the world.

This project present analysis and design if multistory

residential building as per INDIAN CODES- IS 1893-

part2:2002, IS 456:2000.and use national building codes. The

analysis is carried out by considering seismic zones and

behavior is assessed by taking type-III Soil condition. In our

project we are considering a plan under zone-III .Seismic

intensity is severe and zone factor is 0.16 at Luck now. can

design of steel and concrete frame, composite beam and

column, steel joints, and concrete and masonry shear wall,

comprehensive and customizable reports are available for all

analysis and design output, and schematic construction

drawings of framing plans, schedules, details, and cross-

section may be generated for concrete and steel structure

ETAB. ETAB contain every aspect of the engineering design

process. The creation of models has never been easy – The

AUTOCAD drawings can be converted directly into ETAB

model & can easily analysis and design of building.

(IJSRD/Vol. 7/Issue 03/2019/177)


Scope

The main scope of study analyzing and design of multistory

residential building.

It is necessary to analyze and design the multistoried

building to ensure safety against seismic force and avoid

it from collapsing.

By doing this project we will come to know some

software of civil engineering related to design and

analysis of structure like ETAB and AutoCAD.

Analyze the behavior of building under the influence of

lateral loads.

Effect Statement:

The high rise buildings now-a- days are provided with soft

storey for parking purpose. When such building is located in

the earthquake prone area, can be subjected to heavy lateral

forces. Due to the presence of soft story in a building, the

lateral load resisting capacity of building decreases, thereby

the stiffness of building decreases. This leads to sudden

failure of structure. To increase the lateral strength and

stiffness of a structure, shear wall are introduced in a

structure, such that the building can sustain under the seismic

loads.

II. REVIEW OF LITERATURE

ABHAY GULERIA (2014):

Present the analysis of the multistoried building using ETAB

reflected that the story overturning moment varies inversely

with story height. Moreover, L- shape, I- shape type building

give almost similar response against the overturning moment.

Story drift displacement increasing with storey height up to

6th storey reaching to maximum valve and then started

decreasing. From dynamic analysis, mode shapes are

generated and it can be concluded that asymmetrical plans

undergo more deformation than symmetrical plans.

Asymmetrical plan should be adopted considering into gap.

SONIA LONGJAM et.al (2014):

Publisher the paper that presents the plan, model, analyze and

design of a vertical irregular shopping building structure of (

G+ 10) storey and investigate its performance under various

lateral loading conditions. The main goal is to assess current

Indian standard design practice and to provide design

guidelines using ETAB , presents the manual design

calculation satisfying the necessary requirements as per BIS

specification as well various Indian standard code

specification

D. RAMYA AND A.V.S SAI KUMAR (2015):

Principal objective of the project is comparative study on

design and analysis of multistoried building (G+10) by

STAAD pro and ETAB software. STAAD pro is one the

leading software for the design of structure. ( G+10) building

is analyzed for finding the shear forces, bending moments,

deflections & reinforcement details for the structural

components of the building ( such as beam, column & slabs)

to develop the economic design. ETABS is also a leading

design software in present days used by many structural

designers." "Analyzed the identical shape the use of ETABS

software for the layout.. finally, an attempt to define the

economical section of ( G+10) multistoried building using

both STAAD pro and ETABS comparatively, by the intensive

study come to know that the Reasonably-priced section “

turned into developed the use of ETAB software program.

B.ANJANEYULU et.al ( 2016 ): studies the analysis and

design of flat slab by using ETABS software, concludes that

flat plate/slab can be design and built either by conventional

reinforced concrete or post tensioning. However, due to

issues mentioned above with post-tensioning construction in

India and its higher cost, conventional reinforced concrete

design should be preferred choice for spans up to 10 meters.

MR. ABHAYGULERIA: has done the work on the this

paper. ETAB is usually used to analyze: skyscrapers, parking

garages, metal & concrete structure, low and high upward

thrust constructing, and portal frame shape The case take a

look at on this paper in particular emphasizes on structural

behavior of multi-storey building for different plan

configurations like rectangular, c 1 and I-shape. Modeling of

15-story R.C.C framed building is done on the ETAB

software analysis.

IV. BUILDING PLAN

Base Plan According To Center Line




Plan Model Line Diagram Create By Autocad

V. METHODOLOGY

1) Step-1: Create a floor plan in AutoCAD.

2) Step-2: Create center line plan & save DXF (Design

exchange format.

3) Step-3: Open the ETAB software and Initial setup of

Indian standard codes.

4) Step-4: Import DXF file in EATB.

5) Step-5: Create grid for required story building.

6) Step-6: Defining of property: First we are defined the

material properties by selecting define menu material

properties. We add new material for our structural

components (beams, columns, slabs) by giving details in

defining. After that we define cross section size by

selecting frame section as required section beam and

column etc.

7) Step-7: Assigning of property: We draw the structural

components using command menu. Draw beam, column,

slab, wall stair and lift by which property assigning is

completed.

8) Step-8: Assigning of supports: By keeping the selection

at the base of the structure and selecting all the columns

we assigned supports by going to assign menu joint/

frame restraints (supports) fixed.

9) Step-9 Defining of loads:

In ETAB all the load consider are first defined and then

assigned.

10) Step-10: Assigning of dead loads: After defining all the

loads. Dead loads are assigned for external walls, inter

walls in staad but in ETAB automatically taken care by

the software i.e. In built.

11) Step-11: Assigning of live loads: Live loads are assigned

for the entire structure including floor finishing.

12) Step-12: Assigning of wind loads: Wind loads defined

and assign as per IS 875:2015 PART-3 by giving wing

speed and wind angle. But since this is a (G+5)

residential building having total height less than 10

meters there is no need of assigning of wind loads or

earthquake loads.

13) Step-13: Assigning of seismic loads: Seismic load are

defined and assign as per IS 1893: 2002 by giving zone

soil type and response reduction factor in X and Y

directions. But since this is a (G+5) residential building

having total less than 10 meters there is no need of

assigning seismic loads.

14) Step-14: Assigning of loads combinations: Using loads

combinations command in define menu 1.5 time of dead

load and live load will be taken.

15) Step-15: Analysis:

After the completion of all the above steps we have

performed the analysis and checked for errors.

16) Step-16: Design: After complete the analysis we had

performed concrete design on the structure as per IS

456:2000 and by using center line diagram the grid

system is given by X and Y co-ordinates.

VI. RESULTS OF ANALYSIS

Analysis of dead loads, live loads, wind loads ( axial load ) ,

and seismic load and by dead load and live loads induced

shear force and bending moment are analysis with diagram of

gravity load , axial load , lateral load ,and longitudinal

reinforcement.




Gravity (dead loads):-

Stair case and lift in 3D view:-




Wind pressure and Acting axial loads:-




Lateral loading on story:-

Seismic effect on building in 3D view:-




For area of longitudinal reinforcement, go to design menu in ETAB, concrete frame design and start design check.

VII. CONCLUSION

1) The selected site for (G+5) residential building should be

in area where all type of amnesties is available.

2) This project is theory based on the limit state method and

this is the best approach for theory, analysis and design

done by the ETAB software.

3) In this project are used buildings by laws, according to

NATIONAL BUILDING CODE 2005.

4) The structure design are based on the ETAB use different

IS code such like for design concrete 456:2000, For

Wind IS code 875:2015 PART3 and For seismic IS code

1893:2002.

5) This analysis and design is providing adequate strength,

serviceability and durability besides economy.

6) The lateral displacement, dead load and live load

(induced shear force, bending moment) Axial force

variations are in picture diagram. If any defects are

induced or beam, columns are fails, the dimension of

beam and column should be changed and reinforcement

detailing can be produced.
