description: After an introduction in chapter one, chapter two reports about the experimental and theoretical state of the art in punching design. From literature, 303 punching tests without shear reinforcement and 270 tests with shear reinforcement were systematically documented in a data base. Additionally, some representative punching design models were judged by the test results. The evaluation of the punching models from literature and comparisons between the punching capacities in design and tests leads to the following questions: (1) Is it possible to solve the pointed differences between the shear reinforced punching models? (2) In which way is the punching capacity appointed by the layout, position, amount and type of anchorage of the shear reinforcement? (3) Which best fit function could be associated to the material and geometrical para meters like the effective depth, concrete compressive strength, flexural reinforcement ratio,...? (4) Is an optimised type of stirrup able to reach the shear capacity of double headed studs or stud rails? (5) Is it possible to simulate the punching load deflection behaviour of shear reinforced flat slabs by non-linear 3-D finite element analysis? In chapter four to nine these questions were discussed based on 22 own punching tests and several non-linear 3-D finite element studies with the software tools MASA and LIMFES. Finally, an empirical design approach is presented which was accepted for German design code DIN 1045-1 in 2002.
