Abstract
The context makes pseudo-static test of two square steel tube recycled concrete column - steel beam nodes and two square steel tube recycled concrete column-rectangular steel tube recycled concrete beam nodes, taking axial compression ratio and beam column linear stiffness ratio as experimental parameter, and studies the characteristics and mechanisms of destruction, hysteresis curves, ductility and stiffness degradation and other seismic performance. The results showed that, compared with the steel beam joint, hysteresis curve of rectangular steel tube recycled concrete beam nodes are fuller, its energy dissipation capacity is relatively strong, its displacement ductility factor can reach 4.32, but the beam joint only can reach 3.51, so its ductility and deformation capacity are pretty good, the degree of stiffness degradation is smaller. As we can know, the seismic performance of rectangular steel tube girder recycled concrete beam node is better than that of steel beam node, it is worthy of further promotion applications.
