INTRODUCTION

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

Analysis is done through using the STAAD-PRO.

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

CODES

IS-456:2000 :DESIGN CODE FOR RCC STRUCTURES

IS-875(PART1) :CODE FOR DEAD LOADS

IS-875(PART2) :CODE FOR IMPOSED LOADS

IS-875(PART3) :CODE FOR WIND LOADS

STATEMENT OF THE PROJECT :

1.Utility of building : Residential buildng2. No of storeys : G+53.Shape of the building: Rectangular 4.No.of staircases : 6 nos5.Type of walls : Brick wall

Geometric details :

Ground Floor : 9.0 MFloor-Floor Height : 3.0 M Height of Plinth: 0.6 M above G.LDepth of Foundation:2 M below G.L

Material details :

Concrete Grade : M25 Grade of steel : HYSD REINFORCEMENT of Grade Fe415Bearing Capacity of Soil : 200 KN/M2

Type Of Construction : R.C.C framed structure

DIFFERENT TYPES OF LOADS ON THE STRUCTURE

Dead loadsImposed loadsWind loads

Dead loadsInvolves selfweight of

RCC slabBeams & columnsPlinthWalls

Imposed loadsImposed also known live loadsLoad over the floor i.e. load of persons it is calculated as 0.2 kN/m2 This load is applied over the length of structure

Wind loadsWind is air in motion

Wind loads are calculated according to IS:875(part 3)

Intensity of wind and exposure are applied in the directions as required

TYPES OF LOADS IMAGE VIEW

Load combinations

The structure should be analysed for combination of loads as in practice we have number of loads in various directions act Some of the combinations to be checked are

1.5(DL+LL)1.5(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 against overturning , sliding , and buckling.

The main objective of the design are

Foundation designColumn design Beam designSlab design

DESIGN PRINCIPLE, ASSUMPTION AND NOTATION ASSUMED

The notation adopted throughtout the work is same as in IS 456-2000ASSUMPTION IN DESIGN

• Using partial safety factors for loads in accordance with clause 36.4 of IS 456-2000

• Partial safety factor for material in accordance with clause 36.4.2 IS 456-2000 is taken as 1.5 for concrete and 1.15 for steel

• Using partial safety factors in accordance with clause 36.4 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/m3ii) 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

Structural designFor slabs,Depth is 130 mm provided & min depth is 90mmFactored Load on slab is 12Kn/m

For beams,after calculations are done.theDimensions of beam is 230*350mmFactored load on beam is 15.87Kn/m

Shape of column is RectangularFor columns, the dimension of column is 230*500mmFactored load on column 1090.10KN

• For footings, the bering capacity of soil is 200Kn/m2To provide the dimension of footing is 1.5m*2.7m

ANALYSISAnalysis is done using STAAD PRO developed by BENTLEY Once the loads and load combinations are assigned to the structure, analysis is to be doneAnalysis is done for RCC structure

Assign the properties of structure

ASSIGN LOADS ON THE SLAB

Load assign on the walls

Assign wind load on the structure

RCC analysisCode is assigned as IS:456-2000

The parameters are assigned to the structure

Commands to be given are

concrete design Member takeoff

Conclusions

Staad pro become more and more critical in the analysis of engineering & scientific problemsThis facilities for the implementations of more effective & professional engineering softwareIt should be affordable to promote their wide spread usage amongst civil engg at a global scale
