摘要

针对某大型复杂结构的地震响应及控制策略进行了研究。首先

建立该结构的整体有限元模型

采用Ritz向量法对结构进行模态分析

研究该复杂结构的振动特性

基于位能加权平均法求解了该复杂结构等效阻尼比;随后

研究了不同布置型式下粘滞消能支撑的受力特点和计算模型;最后.对该结构进行减振设计

分析了不同消能支撑布置形式下的减振效果。结果表明

采用消能减震装置能有效降低复杂结构的地震响应

且并不改变结构体型;同等减震效果前提下

采用人字形支撑比采用斜撑更为经济。本文工作可供类似的大型复杂结构减震设计参考和借鉴。

Abstract

In this paper

the seismic response and its control strategy of a large complex structure are studied. Firstly

a finite element model of the structure is established

and the vibration properties are studied by using Ritz vector method.Then the damping ratio of the complex structure is obtained using weighted average potential method.Secondly

the mechanical properties of viscous energy dissipation braces of different types and the calculation model are studied.Lastly

the structural control plans for this structure are designed

and the reduction performance of different plans is analyzed.The results shows that the seismic response can be reduced effectively by configuring energy dissipation device and at the same time the architecture modeling does not need changing.Also it can be concluded that compared to the diagonalbraces

using chevron-braces is much more economical.The study of this paper can provide an important refcrence for the analysis of the structural control of large complex structures.
