摘要

本文以一种轴向拉压型金属阻尼器为研究对象，介绍了轴向拉压型金属阻尼器的结构构造及其理论计算方法；进行了抗震性能测试，得到了轴向拉压型金属阻尼器的屈服位移、屈服荷载及屈服刚度，并分析了其耗能能力；研究了轴向拉压型金属阻尼器在体外预应力自复位结构中的应用。研究结果表明：轴向拉压型金属阻尼器利用腹板轴向拉压耗能，避免了连接构件的局部损坏；安装方式与黏滞阻尼器相同，安装方便、易于更换；轴向拉压型金属阻尼器具有提供结构附加刚度，控制结构位移，耗能显著的优点。

Abstract

The constructional detail and theoretical calculation of a kind of axial compression-tension metallic damper are introduced. The yield displacement, yield load and yield stiffness of the axial compression-tension metallic damper were obtained through the quasi-static test, and its energy dissipation capacity is analysed. The application of the damper used in External Prestressing Self-centering Frame (EPSCF) is researched. The results indicate that (1) the axial tension-compression metallic damper dissipates energy through the deformation of its web plates, and the damages occurred on the adjacent components can be avoided; (2) the installation type of this metallic damper is the same as the viscous damper, it can be conveniently installed and easily replaced; (3) the axial compression-tension metallic damper has the advantages of promoting additional stiffness, controlling drifts and dissipating seismic energy.
