Earthquake seismic design 7.
Reinforced concrete gravity retaining wall.
Reinforced concrete retaining wall type 1 and 1sw concrete cantilever wall with flat backfill and flat front face in western wa.
The base is also divided into two parts the heel and toe.
Building codes and retaining walls 5.
Refer to figure a 4 for the mass or weight calculations.
Designed for effective peak ground acceleration of 0 51g d 10 15 reinforced concrete retaining wall type 2 and 2sw concrete cantilever wall with flat backfill and sloping front face in western wa.
Reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.
Forces on retaining walls 6.
Retaining wall can be built with masonry along with reinforced concrete.
The following are the main types of wall.
Thus it is also called gravity retaining wall.
The heel is the part of the base under the backfill.
They consist of a relatively thin stem and a base slab.
Reinforced retaining walls reinforced concrete and reinforced masonry walls on spread foundations are gravity structures in which the stability against overturning is provided by the weight of the wall and reinforcement bars in the wall.
Retaining walls are utilized in the formation of basement under ground level wing walls of bridge and to preserve slopes in hilly terrain roads.
Cantilever retaining walls are constructed of reinforced concrete.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
The reinforced concrete retaining wall resists the lateral pressure by structural action such as bending and results in thinner section.
The weight of the retaining wall including the gravity loads within it plays a vital role in performing the stability check.
Pier and pile foundations 11.
It s not dependent on tie black or grid systems for wall stabilization.
It s a gravity type wall that uses the mass of the concrete materials compacted within cells for structural stability.
A semi gravity retaining walls additional loading case in the case of semi gravity concrete retaining walls such as standard plan type 1 there is an additional loading case considered.
Criblock is a reinforced concrete retaining wall system.
Soil bearing and stability 8.
In case of masonry retaining wall the thickness of wall increases with height because masonry resists the lateral pressure by its weight.
This greatly minimizes excavation and back filling required by other retaining wall systems.
Wood retaining walls 14.
Use much less concrete than monolithic gravity walls but require more design and careful construction.
One is the check for an overturning moment and the other one is the check for sliding.
There are two checks to consider the stability of the retaining wall.

Gabion walls 16.
The toe is the other part of the base.
Counterfort retaining walls 12.
The base is divided into two parts the heel and toe.
Reinforced cement concrete retaining wall cantilever type maximum 6 0 meter height including column load in line.
