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 gravity retaining wall.
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.
The heel is the part of the base under the backfill.
Gabion walls 16.
Building codes and retaining walls 5.
Wood retaining walls 14.
Refer to figure a 4 for the mass or weight calculations.
The toe is the other part of the base.
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.
Cantilever retaining walls are constructed of reinforced concrete.
One is the check for an overturning moment and the other one is the check for sliding.
Earthquake seismic design 7.
It s a gravity type wall that uses the mass of the concrete materials compacted within cells for structural stability.
Reinforced cement concrete retaining wall cantilever type maximum 6 0 meter height including column load in line.
Thus it is also called gravity retaining wall.
Pier and pile foundations 11.
The heel is the part of the base under the backfill.
It s not dependent on tie black or grid systems for wall stabilization.
There are two checks to consider the stability of the retaining wall.
Counterfort retaining walls 12.
Soil bearing and stability 8.
The weight of the retaining wall including the gravity loads within it plays a vital role in performing the stability check.
Reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.
Retaining walls are utilized in the formation of basement under ground level wing walls of bridge and to preserve slopes in hilly terrain roads.
Designing the cantilever wall stem 9.
Reinforced concrete retaining wall type 1 and 1sw concrete cantilever wall with flat backfill and flat front face in western wa.
The reinforced concrete retaining wall resists the lateral pressure by structural action such as bending and results in thinner section.
Retaining wall can be built with masonry along with reinforced concrete.
Concrete cantilever retaining wall.
The following are the main types of wall.
This greatly minimizes excavation and back filling required by other retaining wall systems.
Forces on retaining walls 6.
The base is divided into two parts the heel and toe.
They consist of a relatively thin stem and a base slab.
Along with load case 1 horizontal backfill and load case 2 sloped backfill of 2 horizontal to 1 vertical and limited to a vertical.
The base is also divided into two parts the heel and toe.
Use much less concrete than monolithic gravity walls but require more design and careful construction.
Cantilevered tilt up walls 13.
