Abstract:
In order to avoid the brittle failure of the welds at the intersection of beam and column flanges under earthquake, a form of honeycomb replaceable plastic hinge joints was proposed to achieve the seismic target of repairable ductility design in moderate earthquakes. Low-cycle repeated loading simulation of the node models of seven different honeycomb energy dissipation ring sizes, one weakened node model with round hole opening, one weakened node model with hexagon hole opening and one ordinary beam-column node model was carried out by the ABAQUS under the same conditions. The hysteresis curve, skeleton curve, stiffness degradation curve, ductility performance and plastic energy consumption curve of each joint were analyzed, and the influences of the width and thickness of honeycomb energy dissipation ring on hysteretic performance of honeycomb replaceable plastic hinge joint were discussed. The results show that the hysteretic curve of the honeycomb replaceable plastic hinge node is full and the stiffness degradation trend is good. The ductility indicators exceed 3.0, so the joint has good seismic performance. Increasing the thickness of the honeycomb energy dissipation ring is more effective than increasing the width of the honeycomb energy dissipation ring, which can effectively improve the deformation capacity, bearing capacity and energy dissipation capacity of the specimen after yield. The deformation capacity and load-bearing capacity of the joint remains in a good state after yielding. The honeycomb replaceable plastic hinge joint protects the beam-column joint weld and effectively achieves the plastic hinge outward movement.
