Abstract:

This paper presents a series of shear tests to investigate the test methods of Perfobond connector. 12 tests were finished to study the distinction of results between the insert test and the push-out test. Other 12 push-out tests were done to study the influence of the plate thickness and the concrete slab thickness on the shear behavior of Perfobond connector. The test results are compared and analyzed, focusing on the load-slip curve, the ultimate load, the shear rigidity and the slip versus the ultimate load. The failure mechanism and the deformation mechanism of Perfobond connector are discussed to explain the distinction of different experimental results. In the push-out tests, it was indicated that the friction on the interface between the steel plate and the concrete slab affects the results little. In the insert tests, the additional moment was produced by the precision of machining and fabrication of specimens and the eccentricity between the center of specimen and the center of load. This additional moment affected the shear behavior during the testing and it was difficult to be avoided in the inset test. The results also show the concrete slab thickness hardly affect the shear behavior. And the plate thickness was proved to have little influence on the ultimate load while it affected the shear rigidity and slip a lot.
