Abstract
Research with respect to robustness of (concrete) structures has gained wide interest due to the partial collapse of some case examples, such as the famous collapse of the apartment building in Ronan Point (UK) in 1968. A very important property of concrete structures with respect to robustness is the rigid connectivity with neighbouring elements. When a continuous concrete slab is excessively loaded or when a certain support is lost due to an accidental event, membrane forces can be activated in order to establish a load transfer to the remaining supports, which can considerably enhance its load-carrying capacity compared to estimates obtained from small deformation theories. Thus, membrane actions can prevent a progressive collapse and increase the robustness of concrete structures. Finite element methods allow to simulate the behaviour of cocnrete plates under these large deformations. Currently, however, different questions remain unsolved in order to properly assess the membrane actions under large deflections, i.e. the influence of the constitutive laws which are implemented, the modelling of connectivity, fracture mechanical aspects under tensile membrane actions, etc. As currently only limited research has been focussing on tensile membrane actions, a novel real-scale test set-up has been developed in order to assess these actions in real-scale concrete plates. The details of this test set-up will be explained and some experimental test results will be discussed. Finally, the results will be compared with numerical FEM analyses and the influence of different model assumptions will be evaluated.
