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?
