In the surrounding area of slab-column connections, high moment and shear stresses arise, which can cause both bending failure and shear failure. Local shear failure of flat slabs, which is called punching, is classified as a nonductile failure. With internal columns of horizontally stiffened structures, the stresses are almost symmetrically distributed. However with edge and corner columns, the fixed-end moment from the rigidity of the framework and the shear force result in an asymmetric stress distribution. The relationship of the shear capacity and the moment transferred, which is called the moment-shear interaction, governs the punching shear resistance of slabs with an asymmetric shear stress distribution. For the design a flat slab, apart from an adequate shear resistance in the punching area, a restriction of the deflection is often authoritative. Prestressing reduces deflection and improves the shear resistance. In order to investigate punching and load bearing behaviour, 11 tests with and without prestressing on edge to column connections using a realistic slab thickness were carried out at the Institute of Structural Concrete at Aachen University of Technology. Based on the test results and on non-linear three-dimensional FE simulations a design model was developed to predict the punching resistance of internal, edge and corner column slab connections taking into account the effect of eccentricity and prestressing. Assuming a linear shear stress distribution along the yield line, a scientific model for punching of flat slabs is presented. The derivation assumes that the transmission of shear forces takes place in the compression zone, and the highest shear stress occurs at column-slab transition. The effect of prestressing on the resistance is described by an arch action model. For edge and corner columns a new simplified formulation to calculate the eccentricity factor b was derived. The final comparison of the method with results of punching tests at internal, corner and edge columns shows that all key parameters including the moment-shear interaction and the prestressing are described almost trend-free.","abstract_html":"Due to their economic and architectural benefits, flat slabs made of reinforced or prestressed concrete are widely used for high-rise and residential buildings.
