摘要

传统铅剪切阻尼器的大变形能力不足，且通常易出现耗能效率偏低及稳定性较差等问题。在普通大行程板式铅剪切阻尼器（LSD-LS）的基础上，提出改进型大行程板式铅剪切阻尼器（ILSD-LS）的构造和设计方法。利用铅的理想刚塑性本构关系，建立了改进型大行程板式铅剪切阻尼器力学模型。通过模拟仿真和性能试验结果进一步验证ILSD-LS比LSD-LS具有更优越的出力、耗能能力和稳定性，且提出的阻尼力计算方法合理准确。考虑普通地震动和长周期地震动特性，对安有ILSD-LS的高层结构进行弹塑性时程分析。结果表明采用ILSD-LS的高层建筑结构减震率较高，且长周期地震动作用下的ILSD-LS减震效果更佳。

Abstract

The large deformation capacity of a traditional lead shear damper is insufficient, and undesirable phenomena such as low damping efficiency and poor stability may occur.Based on the design scheme of the normal lead shear damper with long stroke (LSD-LS), the construction and design method of an improved plate lead shear damper with long stroke (ILSD-LS) was proposed.Based on the ideal rigid-plastic constitutive law of lead, a mechanical model of the ILSD-LS was established.Compared to LSD-LS, ILSD-LS has better damping force, energy dissipation capacity and stability according to the results of simulation and experiments, and the method of calculating damping force is more reasonable and accurate.The nonlinear time history analysis of a typical high-rise structure with ILSD-LS was carried out by considering the characteristics of ordinary ground motion and long period ground motion.Numerical results indicate that seismic response of a high-rise structure with ILSD-LS is significantly reduced even when subjected to long period ground motion.
