INTRODUCTION

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

Live loads and dead loads are taken into consideration and analysis is done manually.

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

STATEMENT OF THE PROJECT :

1.Utility of building : Residential building

2.Shape of the building: Rectangular

3.Type of walls : Brick wall

4. No . of flats for each floor : G+14

Geometric details :

Floor Height : 3.0 M

Height of Plinth : 0.6 M above G.L

Depth of Foundation : 6 ft below G.L

Material details : Concrete Grade : M15, M20

Grade of steel : HYSD

REINFORCEMENT of Grade Fe415

Bearing Capacity of Soil : 400 KN/M2

Type Of Construction : R.C.C

framed structure

DIFFERENT TYPES OF LOADS ON

STRUCTURE

Dead loads

Imposed loads

Wind loads

Dead loads

Involves self weight of

RCC slab

Beams & columns

Plinth

Walls

Imposed loads

Imposed also known live loads

Load over the floor i.e. load of persons it

is calculated as 0.5 kN/m2

This load is applied over the length

of structure

Wind loads

Wind is air in motion

Intensity of wind and exposure are applied

in the directions as required

TYPES OF LOADS IMAGE VIEW

Load combinations

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

Some of the combinations to bechecked are

DD + LL = 1.5

DD + LL + WL = 1.2

Density of materials used

MATERIAL DENSITY

i) Plain concrete 24.0 KN/m3

ii) Reinforced 25.0 KN/m3

iii) Flooring material 20.0KN/m3

iv) Brick masonry 19.0KN/m3

OBJECTIVES OF STRUCURAL DEIGN

Structure designed should satisfy the

criteration of ultimate strength.

Structure should satisfy the serviceability

It should satisfy the stability against

overturning , sliding , and buckling.

The main objective of the design are

Foundation design

Column design

Beam design

Slab design

Structural design

For slabs , Depth is 120 mm provided

Factored Load on slab is 9KN/m

For beams, after calculations are done. the

Dimensions of beam is 230*420mm

Shape of column is Rectangular

For columns, the dimension of column is230*350mm & 230*450mm

For footings, the bearing capacity of soil is

400Kn/m2

To provide the dimension of footing is

2000*2000mm

DESIGN OF THE SLAB

If Lx/Ly < 2 two way slab.

> 2 one way slab.

LOADS ON SLABS :

Dead load = thickness * unit weight of concrete.

Live Load for slab = 2.5

CALCULATION OF B.M:

M x = α x W Lx2

M y = α y W LY2

Check for depth d = √ ( Mu/2.7*b)

REINFORCEMENT :

Mu = 0.87 f y A s t d [1- Ast*fy/bd*fck]

• Max Dia of the bars = 10mm

• Spacing of the bars 300 mm c/c

• CHECK FOR DEVELOPMENT LENGTH :-

Id = (Øσs)/(4Ʈbd)

• CHECK FOR SHEAR

Vu / b d

DESIGN OF BEAMS

Max Dimensions of the beam

230*420mm

230*520mm

Max Dia of the beam = 12mm HYSD

bars.

Clear cover of the beams = 25mm.

DESIGN OF COLUMNS

• Max dimensions of the columns

230*350mm

230*450mm

• Max diameter of the bar = 16mm

• Clear cover = 40mm

FOOTINGS

STAIR CASE

Type : Open – newel stair case

No. of flights = 3

No. of steps for flight = 7

ANALYSIS

Analysis of frames is done by using KANIS Method.

The KANIS Method to be simple for multi storeyed building.

Analysis is done for RCC structure

M ab=MF ab +2M’ab +M ’ba

M ba=MF ba +2M’ba +M’ ab

DESIGN OF WATER TANK

Capacity required 32000 lit

wall thickness 200 mm

Area of the tank 2.6 x 3.6 m2

Total Height of the water tank 3.96 m

Total load 4 KN/M2

Reinforcement provided 8 mm Ø bars at

240 mm c/c

RCC analysis

Code is assigned as IS:456-2000

The parameters are assigned to the structure

Commands to be given are

concrete design

Conclusions

It is Manual design.

we can do this analysis within no time but

the basic thing is to know the concept

behind it.

The same result can be achieved using

the software like “Staad-Pro”.
