Retaining Wall Reinforcement Design Example

Retaining wall can be built with masonry along with reinforced concrete.
Retaining wall reinforcement design example. Retaining wall design proceeds with the selection of tentative dimensions see fig 8 3 which are then analyzed for stability and structural requirements and revised as required. 125 retaining walls example 3 16 design of a cantilever retaining wall bs 8 110 the cantilever retaining wall shown below is backþlled with granular material having a unit weight of 19 knm 3 and an internal angle of friction of. Before we proceed with the design it is important for the designer to know the geometric variable and parameters of the retaining wall. Cantilever retaining wall design home new exit properties design parameters wall design foundation wall dimensions analysis seismic design seismic parameter seismic analysis reinforcement parameters spacing finish.
Two equations are developed in this section for determining the thickness reinforcement required to resist the bending moment in the retaining wall components stem toe and heel. Figure a 2 retaining wall geometric variables where. In instance of masonry retaining wall the thickness of wall enhances with height for the reason that masonry opposes the lateral pressure by its mass. As a result it is also known as gravity retaining wall.
