ANALYSIS OF PUNCHING SHEAR FAILURE OF RC SLABS USING NON-LINEAR FINITE ELEMENT METHOD

Abstract

The applicability of 3D non-linear FEM, which has been developed by the authors, on the punching shear failure of RC slabs was studied.
In this paper, experimental results of thin RC slabs, subjected to a concentrated load at various position, and relatively thick RC slabs, loaded through walls or columms connected on the slabs, were compaired with the analytical results using the FEM program.
It was shown that authors' FEM analysis are able to well estimate the punching shear failure of RC slabs, interms of shear strength, diagonal cracking pattern and load-deflection relation.
