摘要
本文就消能减震结构设计参数,即消能部件的支撑刚度、层间最大阻尼力与结构层间屈服力比值等恢复力模型参数的选取进行了讨论。通过对消能装置的耗能特性理论分析,导出了消能装置产生的层间等效阻尼比与这些参数的关系曲线,建议了这些参数的合理取值范围。同时通过对两个消能减震试验结果的分析,验证了本文建议的参数取值的合理性。
An analysis is carried out for the design parameters of the energy dissipation structures. The energy dissipation property of the damping device hysteretic model is studied. The design curves of equivalent damping ratio to the brace stiffness,and ratio of maximum damping force of the damping device to the inter-story yield shear force of the structure are proposed. Some suggestions are presented for the reasonable value range of the design parameters. It is verified by one pseudo-static test and one shaking table test of energy dissipation structures.
