In conjunction with the increasing requirements for thermal protection and energy efficiency, special attention has to be paid to the connection of the slab to the monolithic wall. Common constructions do not meet the still rising energy and heat insulation demands. Therefore, a thermal optimization of the wall-slab-junction is required, which is carried out by means of a significant reduction of the bearing length of the slab. Hence, an investigation on the consequences of such a reduction is underway at the Chair of Structural Design at TU Dresden. In the context of the project, the effects of the reduction of the bearing length on the stability and usability of a system and the failure of partially supported slabs in the ultimate limit state are to be investigated analytically, numerically and experimentally. Based on the results, a suitable model for the structural analysis of partially supported slabs will be developed, which allows for the reliable structural design of reduced bearing lengths.
