Abstract: The results and interpretations of push-out tests on shear connector devices for steelconcrete composite structures/bridges carried out in the Stevin laboratory are presented.
The devices under investigation are headed studs, perfobondstrips, oscillating perfobondstrips, waveform strips and T-connectors. The oscillating-perfobondstrip, waveform strip and T-connector have specially been developed for this research project. Different concrete grades and types are used, like ordinary concrete, lightweight concrete, high strength concrete and lightweight high strength concrete, with and without steel fibres. The tests are done as specified in EuroCode 4 for standard push-out test. Large differences in ductility and strength between the various connector devices and concrete types have been observed. Sometimes unexpected behaviour occurred during testing, like brittle splitting failure in case of the (oscillating) perfobondstrip in normal concrete.
A direct comparison for a specific shear connector device in combination with a certain concrete grade/type is possible. Although the number of samples in a test series is limited, it is still realistic to draw conclusions with respect to their strength/ductility based on EuroCode 4.
