Retaining Wall Steel Reinforcement
Us reinforcing steel system when splicing a 5 reinforcing steel bar which has a diameter of 0 625 inches the minimum lapped splice length is.
Retaining wall steel reinforcement. Reinforced earth is the reinforced earth company s flagship mse retaining wall product first introduced in the united states in 1971. Hence effective depth d is d 400 cover 2 400 35 20 2 355 mm. Fs s knm 3 14 7917 5 3 1847 effective depth assume diameter of main steel 20 mm. 40 x 0 625 inches 25 inches.
Cut the vertical reinforcement steel bars for the lower storey so that they are flush with the top of that wall. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria. Calculate the lateral earth. Calculate the distance to steel and the area of the steel reinforcement for the toe section of the base of a concrete cantilever retaining wall.

Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab. The system s soil reinforcements are inextensible high adherence ha steel reinforcing strips or ladders which are bolted to tie strips embedded in precast concrete facing panels.
These walls cantilever loads like a beam to a large structural footing converting horizontal pressures from behind the wall to vertical pressures on the ground below. Calculate the development length for the steel reinforcement of the stem section of a concrete cantilever retaining wall.
