为研究新型预压弹簧自恢复耗能支撑结构的自恢复性能和耗能性能,对预压弹簧自恢复耗能支撑在低周往复荷载作用下的滞回特性进行了模拟研究,分析了自恢复耗能支撑旗形滞回曲线的特点,给出了支撑恢复力的计算方法,建立了基于Bouc-Wen模型的预压弹簧自恢复耗能支撑恢复力模型,并与ANSYS数值模拟结果进行了对比,结果表明建立的恢复力模型可准确模拟支撑在动力荷载作用下的力学性能。恢复力-位移曲线整体吻合程度较高,该恢复力模型对自恢复耗能支撑结构的设计及抗震性能研究具有较好的参考价值。 In order to study the self-recovery performance and energy dissipation performance of self-restoring energy-dissipative support structure of new pre-compression spring, the hysteretic behavior of self-restoring prestressed spring self-restoring energy dissipation under low cyclic loading was simulated. The calculation method of supporting restoring force is given based on the characteristics of energy-supporting flag-shaped hysteresis curve. The restoring force model of self-restoring prestressed spring based on Bouc-Wen model is established and compared with ANSYS numerical simulation results The results show that the established restoring force model can accurately simulate the mechanical properties of the support under dynamic load. The restoring force-displacement curve has a high degree of conformity as a whole. The restoring force model has a good reference value for the design of self-restoring energy dissipating support structure and seismic performance.
