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,

$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,

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 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,

$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
