Experimental Study on Hysteretic Performance of Assembled Steel Energy-dissipating Hinge

A new type of steel energy-dissipating hinge, which was used to connect prefabricated beam and column in the frame structure, was proposed to meet the seismic design demand of "strong connection". A steel energy-dissipating hinge was tested under cyclic loads to study its seismic performance and damping effect. The experimental results were presented in terms of failure mode, hysteretic curve, load-bearing capacity, stiffness and ductility. The test results show that the hysteretic curve of this kind of steel energy-dissipating hinge is full, strength degradation is not obvious and energy dissipation ability is strong, which indicate that this kind of steel energy-dissipation hinge has good bearing performance and hysteretic characteristics.
