Generally, No. 4 and smaller bars are used for flexural reinforcement in slabs, because larger wires tend to be bent out of position by workers walking on the reinforcement during construction.

Determine As,min for the following beam given that f’c = 5,750 psi and fy = 60,000 psi.

Paso 2 (3 pts) (1 pt per item: Correct words with omitted or misplaced written accents will receive 0.75 pts) What other activities can Alicia enroll in this semester? Fill in the blank with the appropriate activity below. Complete each sentence to describe the picture with the appropriate expressions using an infinitive form of a verb or a noun in each sentence. Note: An infinitive form of a verb is a word that ends in -ar, -er, -ir, for example, “estudiar”. A noun is a word that names a person, place, or thing. For example, “(el) fúbol”. 

A simply-supported beam has a 2 kip/ft uniformly-distributed load over the entire 12-ft span. What is the magnitude of the shear force at midspan?

Equal shearing stresses exist on both the vertical and horizontal planes through an element.

If φVc = 43 kip and Vu = 54 kip, are stirrups required?

Vertical stirrups are effective in beams resisting shear reversals, such as seismic loads.

Assuming Vs exceeds 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let b1 = 30 in., b2 = 15 in., d1 = 4 in., and d2 = 45 in. There are three No. 6 longitudinal tension bars and No. 3 stirrups at 12 in. o.c.

Assuming Vs does not exceed 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let b = 13 in. and d = 49 in. There are four No. 7 longitudinal tension bars and No. 3 stirrups at 12 in. o.c.

Axial compression tends to increase shear strength.
