The Simulation of Punching Shear Behavior of Spread Footing with Specially Shaped Columns

Xiufeng Xu and Zi’ang Kong
Abstract—In order to study on the punching shear behavior of spread footing with specially shaped columns, the spread footing with rectangular column was simulated by MSC.Marc firstly, the load-deflection curve and punching process of the simulation is consistent with the experiment. Then simulations of foundations with cross-shaped, T-shaped and L-shape column were carried out based on this, which show punching bearing capacity of the cross column is greater than that of T and L. Furthermore, these footing with specially shaped columns were calculated according to ACI 318 and LIU Wenting’s paper, punching shear strength of cross-column, T-column and L-column of the simulation are 1.21 times, 1.12 times and 1.09 times as high as the calculation. The comparison between calculation and test of 99 spread footings with rectangular column show that the test values are 1.25, 1.21, 1.42 times the calculation by CB5007, BS8110 and EN 1992. Therefore, the simulation in this paper is credible and can be used for the in-depth analysis of the spread footing.

Index Terms—cFinite element modelling, specially shaped columns, spread footing, punching shear failure.
