摘　　要：通过对典型枓栱的模型的低周反复荷载试验,研究了枓栱侧向刚度的退化规律。试验得出枓栱的力-位移滞回曲线及骨架曲线,并拟合出了力-位移的关系方程和枓栱恢复力模型。由实验结果给出枓栱侧向刚度的线性强化性能。研究结果为古建筑的抗震性能研究和修缮加固提供了理论。Experiment on the typical model of a Dougong was carried out under low cyclic reversed loading in order to study the lateral stiffness degradation law of the Dougong. Force-displacement hysteresis loops and skeleton curves of the Dougong are obtained to fit out the force-displacement equation and restoring force model of the Dougong. The tested results reveal the linear-hardening behavior of lateral stiffness of the Dougong, and also provide a theoretical basis for the study on the seismic performance, remedy and strengthening of ancient buildings.
