Abstract:The seismic performance of end plate bolt connection wave beam web-high-strength stirrup constraints of concrete column nodes was studied. Two sets of four full-scale nodes were designed and pseudo-static experiments were carried out under low reversed cyclic loading. By observing the stress, deformation, failure process and failure pattern of the node model, the bearing capacity, deformation capacity and energy dissipation capacity were analyzed, the reliability of the new node was verified. The results show that under the function of beam end stiffening plate, the plastic hinge of wave beam web moves outboard to exert its energy dissipation capacity, which can provide reliable theoretical basis for engineering application of the new node.

Keywords:wave beam-column web node; high-strength bolt; pseudo-static experiment; seismic performance
