Title: Punching Shear Strength of Composite Construction

Abstract:The type of composite construction examined consists of an inner and outer steel skin with the annulus between the skins filled with concrete. An experimental program was conducted on 32 composite shells. All the shells were subjected to an increasing concentrated load applied to the top surface at midspan. A wide range of parameters was studied to obtain a preliminary appraisal of their effects on the punching shear strength of the composite shells. These parameters were thickness of the steel skins, type and strength of the concrete filler, size of the patch load, shell curvature, and boundary conditions. The results of these tests are presented and discussed, and the code methods for predicting the punching shear strength of reinforced concrete slabs are compared with the results obtained from this study.
