Abstract
There is an ever increasing need to construct new structures to house the
’er increasing population. Traditional structures built by the beam-column
chnique have a major shortcoming of consuming large amounts of reinforcing
eel. The market prices of reinforcing steels have dramatically soared in recent
ears both nationally and internationally. On the other hand, the traditional
aring wall system needs less steel reinforcement but consumes large amounts
f steel in its foundations. Folded foundations have been used as an alternative
o the conventional flat shallow foundations. They can be geometrically shaped
n elevation, triangular, cylindrical, parabolic, etc., for continuous footings such
s strip footing. A vital element in promoting the return back to the bearing wall
ystems is reducing the amount of steel in their foundations. This thesis is much
eeded in national project for youth housing. This project will be constructed in
aany new towns in Egypt depending on bearing wall system. Therefore, the
urpose of the current thesis is not just reducing the amount of reinforcing steel
the bearing wall foundations, but rather minimizing this amount through
hoosing the most effective strip footing shape. A well known concept in
reinforced concrete is the ability of concrete to sustain high compressive
uresses, while the steel is only needed in tension zones. Consequently,
inimizing or eliminating the tension zones on the tested foundation shapes is
e main goal of the current research to minimize the needed steel
einforcements.
The thesis will be conducted in two main phases. The experimental phase
f the study will test different strip footing shapes underlain by medium dense
and. The experimental testing program will verify the numerical studies and
Iarify the difficulties which may arise during the construction of the proposed
folded strip footings. The numerical phase of the study is performed using the.
