| description | ► Analytical model to predict the punching shear resistance of concrete slabs. ► Analytical model based on the mode-II fracture properties. ► Punching shear failure is caused by quasi-brittle cracking of concrete. ► Punching shear strength is strongly influenced by the thickness of concrete slab.
In this paper an analytical model is presented to predict the punching shear resistance of concrete slabs using fracture energy concept. The mode-II fracture parameters are obtained by conducting the experiments on double edge notched specimens. The model predicts the force displacements resistance during punching and the stress distribution along the cracked surface. Experimental investigation on punching shear resistance of concrete slabs is also reported to compare the model. The punching shear tests showed that the thickness of slab had a strong influence on the punching shear strength and also very good agreement between the predicted and experimental results. |
