Abstract

In this paper, shear performance test is performed on 9 specimens to explore slab-slab joint with quick construction speed and low cost. Where, the triangular bar specimen uses 1000MPa high-strength steel bar as the shear reinforcement. The test results show that: the groove specimen has the highest bearing capacity, but experiences brittle shear failure; the triangular bar specimen with 1000MPa high-strength steel bar has high bearing capacity and good ductility. The new connection mode transmits shear force through groove, triangular bar to achieve rigid connection with ductility. At the end of this paper, it is proposed that prestressing can be applied to increase rigidity of the floor. Providing test basis for engineering design, the results of this paper are used in a 500,000 square meter integral assembly project.
