| 摘 要： | 通过时程分析法多次循环寻找结构的最大层间位移，不断修正各楼层粘弹性阻尼器的储存刚度和损耗刚度，来优化粘弹性阻尼器沿结构竖向的布置。并利用ANSYS的APDL语言编制优化程序，以一个六层钢框架为例进行了优化，得到了各楼层粘弹性阻尼器的参数及分布规律；并通过多种工况的分析，验证了这种优化方法的可靠性，并说明其减震性能很好。

| Abstract: | The paper introduced an optimization analysis method of structures with viscoelastic dampers(VED),which is based on calculating maximum interstory drift and amending parameter of VED by time history analysis method.An optimal program is made.It is used to determine the optimal parameters and location of VE dampers in a steel frame structure.The result indicates the method is feasible and reliable.It is also found that the shock absorption effect of the VE dampers is best when the parameter of VE dampers is ... |
