Abstract:This paper explains the physics behind some of the reinforced concrete structural integrity provisions in the 2014 New York City Building Code (NYCBC). These provisions were developed from 2003 to 2007 and adopted in the 2008 NYCBC and have been in effect since then. The provisions studied are the ones related to the mitigation of punching shear failure. This paper shows that the additional bars provide resistance to punching shear failure that covers nearly all dead load and reasonable and different amounts of live load. The provisions are not onerous, having been used in NYC for the last six years and the authors believe they represent an improvement over the prescriptive and non- quantified ACI provisions.
