UHPC in composite construction
The paper summarizes the results of a research program (DFG priority program SPP 1182) involving the testing of push-out specimens and composite beams with innovative continuous shear connectors in ultra-high performance concrete. In the push-out tests the load-slip behavior of the shear connectors was evaluated and compared for various parameters. The parameters included the steel fiber content, the transverse reinforcement ratio and the thickness of the puzzle strip. The test results indicate that the steel fiber reinforcement ratio has only a minor influence on the load carrying capacity whereas the transverse reinforcement ratio is more vital. The beam tests are focused on the moment carrying capacity and the transition of the shear forces across the joint between steel and concrete The results of one of the tests with an innovative cross section are presented as an outlook.
