Prediction of Punching Shear Failure Behaviour of Slab-Edge Column Connections with Varying Size and Location of Openings
A numerical analysis using the non-linear Layered Finite Element Method (LFEM) is undertaken to predict the effect of openings on punching shear behaviour of slab-column connections with shear stud reinforcement. In all, eleven (11) models are investigated through three parametric studies including varying the opening size, varying the opening location in the front face of the column, and varying the column aspect ratio. The numerical results covering the load-deflection response, ultimate shear strength, deformation and crack patterns are examined in some detail. Where applicable the predicted ultimate shear strengths are compared to the experimental results. The LFEM is also compared to the Australian Standard and American Concrete Institute Code. The performance of the LFEM and the code methods in predicting the punching shear failure behaviour of slab-column connections are discussed.
