Finite Element Prediction on the Post-Punching Behavior of Slab-Column Connections

Abstract:

The post-punching behavior of slab-column connections with the employment of engineered cementitious composite (ECC) material was investigated. Two specimen models were modeled and simulated in the finite element program to predict the limit of punching shear resistance and post-punching shear behavior due to lateral load. The first specimen was constructed using regular concrete as the control specimen. The second specimen was built with ECC material at the local thickening at drop panel area and regular concrete at the rest of the members. ECC material was selected due to its superior performance with high tensile strain of more than 2% through multiple micro-cracking with width of less than 80 μm. The results highlighted an improvement of shear capacity and post-punching behavior at the second specimen. Furthermore, compressive damage of post-crushing response on the second specimen also indicated less crushing phenomenon at the critical perimeter than that of the first specimen.
