1. The reinforced concrete cantilever retaining wall in Figure 1 is made with 3000 psi normalweight concrete and reinforced with Grade 60 galvanized steel. The main reinforcement resists flexural stresses in the stem and is specified as #7 bars every 18 in along the length of the wall. The distribution steel distributes stresses along the length of the wall and is specified as #4 bars at 12 in spacing. The concrete cover is 1.5 in everywhere. Calculate the development length for the main reinforcement using the basic equation (ACI 318-19: 25.4.2.4). Assume no transverse reinforcement (Ker 0). Is the main reinforcement embedded deeply enough in the footing to fully develop its yield strength in tension?

Question
1. The reinforced concrete cantilever retaining wall in Figure 1 is made with 3000 psi normalweight
concrete and reinforced with Grade 60 galvanized steel. The main reinforcement resists flexural
stresses in the stem and is specified as #7 bars every 18 in along the length of the wall. The
distribution steel distributes stresses along the length of the wall and is specified as #4 bars at 12 in
spacing. The concrete cover is 1.5 in everywhere. Calculate the development length for the main
reinforcement using the basic equation (ACI 318-19: 25.4.2.4). Assume no transverse reinforcement
(Ker 0). Is the main reinforcement embedded deeply enough in the footing to fully develop its yield
strength in tension?
