A nominal 8 x 32 in. simply supported CMU beam is reinforced with one No. 8 bar Grade 60 reinforcement in tension with d = 28 in. The beam carries a dead load of 1.1 k/ft (includes beam self-weight) and a service live load of 1.2 k/ft. The effective span of the beam is 16 ft. Assume f’m = 2,500 psi and that the beam is safe in flexure. Design the shear reinforcement, if any, for this beam. Make sure you make practical recommendations.

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.
