| Abstract: | Investigations on the Punching Behaviour of RC Footings. The punching shear capacity of footings varies significantly for different codes. The amount of the soil reaction to be deducted from the punching load differs from one code to another. The aim of the present investigation is to derive an advanced design model for footings taking into account the soil‐structure‐interaction. The results of five punching tests on reinforced concrete footings supported on soil are presented. The experimental results indicate that the angle of the shear failure plane is steeper than observed by punching tests on flat slabs, and the shear slenderness seems to affect the punching shear capacity significantly. In order to reach a better insight of the load carrying capacity, nonlinear finite element simulations are performed. Based upon the findings and a test data bank an advanced design model is derived, which is based upon the DIN 1045‐1 provisions. |
