Abstract

Punching shear often controls the required slab thickness or column size of flatplate slabs. This paper presents the results of an experimental investigation of the punching shear strength of post-tensioned concrete slabs with rectangular and L-shaped columns. The test results are compared with ACI equations for punching shear strength. An analysis accounting for the cracking at the critical sections is also presented which provided a better prediction of the punching shear strength. Good correlations between what was predicted and the actual experimental results have been achieved.
