1. A rectangular beam section is 10 in. wide and has a structural depth of 13.5 in. Reinforcement consists of two No. 8 bars. Given that the strength normal weight concrete is 4000 psi and there is NO shear reinforcement in the section, determine the nominal shear capacity allowed by the ACI Code. (5 pt) (Hint: No web reinforcement, so Vc = 8λ¸^(pw)¹/³√fcbwd shall be used).

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