Concrete slab punching shear calculation

WebOct 11, 2024 · What is the concrete contribution to punching shear when shear reinforcement is present? Answer: As stated in the SAFE design manual, and prescribed by ACI 318 requirements, SAFE uses 2*sqrt (f'c) for shear links (rebar) and 3*sqrt (f'c) for shear studs. Why is the punching-shear check not displayed? WebMay 29, 2024 · Punching shear failure is one of the typical concrete slab collapses. Punching shear may result from a concentrated load or reaction acting on a relatively small area. For ease of reference, the following description of the task solution is based on the punching failure verification model presented in EC2 ( 2006 )—see Fig. 1. Fig. 1
