1. Consider the shear diagram below for the simply supported rectangular beam. Compute the following, assuming that #3 stirrups (L) will be used for shear reinforcement. A #3 bar has a cross-sectional area of 0.11 in². Assume normal weight concrete, fy = 60000 psi, and fo = 4000 psi. You may also assume that the beam's self-weight is included in the dead load provided. Per ACI 9.6.3, shear reinforcement is required when V₂ > Vc. a. At what distance from the left support can shear reinforcement end? b. At what distance from the left support can theoretical spacing be taken as 16"? You do not need to check whether 16" is within maximum allowable values. (Recall: Vu= Vn = OVc + Vs, 0 = 0.75) WD = 1 k/ft W₁ = 2 k/ft 28 ft Criteria 22.5.5 V for nonprestressed members 22.5.5.1 For nonprestressed members, V, shall be calcu- lated in accordance with Table 22.5.5.1 and 22.5.5.1.1 through 22.5.5.1.3.

Design criteria for structural loading

The different loads such as loads due to self-weight (dead load) and external loads such as live load, wind loads, seismic load, snow load, and other loads and load combinations that influence the design of a building are called structural loading. The nature of the applied load differs from changes in the location, design, and type of materials used. The design criteria require that structures must be designed and constructed to be able to withstand all load types that are expected to act upon the structure and render its usage for the designated purpose. The structural members such as beams, slabs, columns, and foundations help the structure to withstand the applied load. There are different institutes such as ASCE and ACI that provide building design codes to assure minimum safety requirements and quality of the structures.
