Objectives

The Objectives of the Project are:-

Carrying out a complete analysis and design o the main

structural elements o a multi&storey building including slabs'columns' shear "alls and oundations

Summary

Our graduation project is a residential building in Gora+hpur

!ail"ay division,

$lace-& Basti

This building consists o ./ repeated loors,

General Approach

Obtaining an architectural design o a regular residential multi&

storey building,

Establishing the structural system or the ground' and repeated

loors o the building,

The design o column' "ind resisting system' and type o

oundations "ill be determined ta+ing into consideration the

architectural dra"ings,

Types o building

Buildings are be divided into- Apartment building

Apartment buildings are multi&story buildings "here three or more

residences are contained "ithin one structure,

Oice building The primary purpose o an oice building is to provide a "or+place and

"or+ing environment or administrative "or+ers,

Concrete 0i*tures

Concrete is a durable material "hich is ideal or many jobs,

The concrete mi* should be "or+able,

%t is important that the desired 1ualities o the hardened concrete

are met,

Economy is also an important actor,

Structural Elements

Any reinorced concrete structure consists o -

Slabs

Columns Shear "alls

Foundations

$ile oundation

Our building is rested on a "ea+ soil ormation "hich

cant resist the loads coming rom our proposed building'

so "e have to choose pile oundation,

$ile oundation

$iles are structural members that are made o steel'

concrete or timber,


31/40

31

Function o piles

As "ith other types o oundation' the purpose o a pile

oundation is-

To transmit a oundation load to a solid ground

To resist vertical' lateral and uplit load

/iles can %e Timber

Concrete Steel

Composite

Concrete piles

General acts

sual length- .4m&/4m

sual load- 344+&3444+

Advantages Corrosion resistance

Can be easily combined "ith a concrete superstructure

Disadvantages

Diicult to achieve proper cuto

Diicult to transport

$ile oundation

$iles can be divided in to t"o major categories-

., End Bearing $iles

% the soil&boring records presence

o bedroc+ at the site "ithin a reasonable depth'

piles can be e*tended to the

roc+ surace

/, Friction $iles

#hen no layer o roc+ is present depth at a site' point bearing piles become very

long and uneconomical, %n this type o subsoil' piles are driven through

the soter material to speciied depths,


34/40

34

$ile Cap !einorcement

$ile caps carrying very heavy point loads tend to produce high

tensile stresses at the pile cap,

!einorcement is thus designed to provide- !esistance to tensile bending orces in the bottom o the cap

!esistance to vertical shear

Although the cement production is environmentally

challenging' the inal product o a reinorced concrete

building is environmentally riendly,
