Assuming Vs exceeds 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let b1 = 37 in., b2 = 12 in., d1 = 6 in., and d2 = 33 in. There are three No. 8 longitudinal tension bars and No. 4 stirrups at 10 in. o.c.

When a beam is supported by a girder or other beam of essentially the same depth, _______ should be provided in the joint.

Compute φVn for the cross section shown. Assume f’c = 3,000 psi, fyt = 60,000 psi, b1 = 23 in., b2 = 12 in., d = 24 in., h1 = 4 in., h2 = 17 in., h3 = 8 in., t = 7 in., and that there are six No. 6 longitudinal tension bars and No. 5 stirrups at 9 in. o.c.

Web reinforcement is normally provided to ensure that the beam reaches the full _______ capacity.

Do stirrups prevent inclined cracks from forming?

For a beam with stirrup hooks, the free end of the bar must extend at least _____ from the hook. Assume b1 = 25 in., b2 = 15 in., d1 = 4 in., d2 = 25 in., and that there are three No. 8 longitudinal tension bars and No. 5 stirrups at 12 in. o.c. The stirrup hooks are 90°.

A simply-supported beam has a 1 kip/ft uniformly-distributed load over the left half of its 11-ft span. What is the magnitude of the maximum shear force in the beam?

Paso 2 (3 pts) Alicia and Luis are still talking about their sport and activities preferences. Complete each sentence with the most appropriate verb in the infinitive. Note: An infinitive form of a verb is a word that ends in -ar, -er, -ir, for example, “estudiar”. 

A concrete floor system with a ratio of the longer to the shorter span length that is greater than or equal to 2 is usually considered a one-way system.

A classmate has suggested a beam design that has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. and is reinforced with 4 No. 7 bars. Assuming a cover of 1.5 in. and a stirrup diameter of 0.5 in., does the reinforcement fit within a single row as suggested?
