Experimental Performance of Effects of Opening on Reinforced Concrete (RC) Flat Plate Slabs

Abstract

The reinforced concrete (RC) flat plate provides a good solution for the roofing system. This method of flat plate construction generally employed at commercial projects. The structural behavior of reinforced concrete flat plate is different from conventional RC slabs as these flat plates are directly supported on columns. The flat plates are more susceptible to reduce load carrying capacity due to openings and also reducing the capacity of punching shear failure. The openings are required in existing slabs due to post installment of cables, sanitary pipes, lift, escalators. This present study involves analyzing the effect of flat plate with and without opening. The parameter studied was load carrying capacity.
