A simply supported, rectangular, reinforced concrete beam having d = 24 in. and b = 15 in. supports a uniformly distributed load wu of 7.50 kips/ft as shown.
The given load includes the beam weight. Assume No. 3 single-loop stirrups. The concrete strength is 4000 psi and the steel is grade 60.
a. Select the stirrup spacing to use at the critical section (d distance from the face of support).b. Determine the maximum stirrup spacing allowed for this beam.c. Using the two spacings determined in parts (a) and (b), devise an appropriate stirrup spacing layout for this beam.
