摘要
In this paper, steel fiber reinforced concrete is used to replace the stirrup in the core of the node to improve the node performance, and reduce the construction difficulty and ensure the node with certain seismic performance. In this paper, through the test of steel fiber reinforced concrete specimens under low cyclic loading cycles, the occurrence and development of joint cracks, the deformation, ductility, energy dissipation and final failure morphology of specimens were studied. The results show that the use of steel fiber instead of stirrups in the core area of high strength concrete can improve crack shape, and increase crack initiation load and deformation, ductility and energy dissipation of joints, and improve the seismic performance of joints to a certain extent.
