INTRODUCTION

Our project is based on the design and analysisof the multi-storied building.

Analysis is done through using the STAAD-PRO.

Notation adopted through out the project issame as in IS-456-2000.

DIFFERENT TYPES OF LOADS ON THE

STRUCTURE

zDead loads

zImposed loadszWind loads


10/35

Dead loadszInvolves selfweight of

zRCC slab

zBeams & columns

zPlinth

z

Walls


11/35

Imposed loadszImposed also known live loads

zLoad over the floor i.e. load ofpersons it is calculated as 0.2 kN/m2

zThis load is applied over the lengthof structure


12/35

Wind loadszWind is air in motion

zWind loads are calculated according to

IS:875(part 3)

zIntensity of wind and exposure are appliedin the directions as required

Load combinations

zThe structure should be analysed forcombination of loads as in practicewe have number of loads in variousdirections act

zSome of the combinations to bechecked are

z1.5(DL+LL)

z1.5(DL+WL)

OBJECTIVES OF STRUCURAL DEIGN

Structure designed should satisfy the

criteration of ultimate strength.

Structure should satisfy the servicablity

It should satisfy the stablity againstoverturning , sliding , and buckling.

DESIGN PRINCIPLE, ASSUMPTION AND

NOTATION ASSUMEDz The notation adopted throughtout the work is same as in

IS 456-2000

ASSUMPTION IN DESIGN

Using partial safety factors for loads in accordance withclause 36.4 of IS 456-2000

Partial safety factor for material in accordance withclause 36.4.2 IS 456-2000 is taken as 1.5 for concreteand 1.15 for steel

Using partial safety factors in accordance with clause36.4 of IS 456-2000 combination of load

(D.L +L.L) 1.5

(D.L +L.L +W.L) 1.2

Density of materials usedMATERIAL Density

i) Plain concrete 24.0 KN/m3

ii) Reinforced 25.0 KN/m3iii) Flooring material (c.m) 20.0KN/m3iv) Brick masonry 19.0KN/m3v) Fly ash 5.0KN/m3

LIVELOADS: In accordance with IS 875-86i) Live load on slabs = 3.0KN/m2ii) Live load on passage = 3.0KN/m2iii Live load on stairs = 3.0KN/m2


19/35

Structural design

For slabs,Depth is 130 mm provided & mindepth is 90mm

Factored Load on slab is 12Kn/m

For beams,after calculations are done.theDimensions of beam is 230*350mm

Factored load on beam is 15.87Kn/m


20/35

z Shape of column is Rectangular

z For columns, the dimension of column is230*500mm

z Factored load on column 1090.10KN

For footings, the bering capacity of soil is

200Kn/m2z To provide the dimension of footing is

1.5m*2.7m

ANALYSISzAnalysis is done using STAAD PRO

developed by BENTLEYzOnce the loads and load combinations are

assigned to the structure, analysis is to bedone

zAnalysis is done for RCC structure

RCC analysis

z Code is assigned as IS:456-2000

z The parameters are assigned to the structure

z Commands to be given are

Conclusions

z Staad pro become more and more critical

in the analysis of engineering & scientificproblems

z

This facilities for the implementations ofmore effective & professional engineeringsoftware

z It should be affordable to promote theirwide spread usage amongst civil engg at a

global scale
