It is reinforced for flexure with three No. 9 (No. 29) bars that continue uninterrupted to the ends of the span. It is to carry service dead load D 1.27 kips/ft (including self-weight) and service live load L -3.70 kips/ft, both uniformly distributed along the span. Design the shear reinforcement, using No. 3 (No. 10) vertical U stirrups. The more approximate...

You are given the task of checking the adequacy of a simply supported slab of 10-inch thickness, 12 ft span. The reinforcement used is #7 rebar at 6 inches on center. The distributed live load on the slab is 600 psf respectively. Assume f’c=3,000 psi, fy=60,000 psi. Determine if the slab is structurally sufficient, and post your detail calculations as well.
The simply supported beam shown spans 20 ft and, in addition to its own weight carries a uniformly distributed service dead load of 1.75 kips/ft and a uniformly distributed live load of 3.0 kips/ft. Five no. 9 bars running the full length of the beam arc used as flexural reinforcement. Assume f,-60,000 psi and fc4000 psi, No. 3 stirrups are used. a. Determine the theoretical spacing of stirrups at the critical section using the detailed expression for the shear strength...
A rectangular beam having b=16 in and d=26 in spans 28 ft face to face of simple supports. It is reinforced for flexure with 6#11 bars that continue uninterrupted to the ends of the span. It is to carry service dead load 2.0 kips/ft (including self weight) and service live load 3.6 kips/ft, both uniformly distributed along the span. Design the shear reinforcement using vertical U stirrups. Economize the spacing of stirrups in appropriate number of bands. Material strengths are...
