| 摘 要： | 基于结构空间杆系-层模型,推导了粘滞阻尼器减震结构的附加阻尼矩阵、动力平衡方程和相对能量方程。在高层建筑结构动力分析程序HBTA中增加对粘滞阻尼器减震结构的非线性动力分析。通过具体算例,验证了本文所建议动力分析方法的正确性,并考察了粘滞阻尼器对结构的减震效果。HBTA程序可以反映结构构件和粘滞阻尼器的内力和变形。对同时包含位移相关非线性和速度相关非线性的结构动力分析做了有益尝试。

| Abstract: | Based on the story model of spatial member, the supplemental damping matrix, dynamic balance equation and relative energy balance equation of structures with viscous dampers are derived. Nonlinear dynamic analysis of structures with viscous dampers is added into the computer program HBTA (highrise building time-history analysis). Examples are provided to validate the dynamic analysis method and observe the seismic mitigation effect of viscous dampers. The inner forces and deformation of structural members and viscous dampers can be given by HBTA. Efforts are made to conduct dynamic analysis including both displacement-dependent nonlinearity and velocity-dependent nonlinearity. |
