摘要:
在建筑物中设置耗能减震装置, 已在抗震领域研究多年, 而阻尼安装位置的优化确是摩擦阻尼器应用
中面临的主要问题之一.相同数量的阻尼器, 不同的布置位置, 将会对主体结构的消能减震作用产生较大影
响.对此, 本文以某八层框架为例, 通过ANSYS 有限元软件对结构进行八度多遇及罕遇地震作用分析, 得出
了结构在无阻尼、循环优化法及遗传算法再优化三种情况下结构的地震响应.计算结果表明, 安装摩擦阻尼器
的消能减震结构抗震性能明显提高;在摩擦阻尼器数量一定的前提下, 通过遗传算法对阻尼器位置布设的进
一步优化有利于减小结构地震响应, 提高结构抗震性能.
Abstract:
Setting energ y dissipato r in the building has been in research fo r many y ears in the seismic field.One o f the f riction
damper applica tion problems is the damper setting place .Ther e is g reat influence o n ener gy dissipation in structure
whether the damper setting place is optimized unde r the same number o f the dampers .Eight deg rees multi-in earthquake
and ra re earthquake dy namic time histo ry analysis was do ne in an eig ht-flo or frame by ANSYS finite element softw are .
Three conditio ns of str uctural dy namic respo nse are obtained:no friction damper , f riction dampe r optimized by cy cled o ptimum
method , and fric tion unde r GA method .The results show that the str ucture , with friction dampe r installed , can
markedly im pr ove the seismic ability , and the optimizatio n o f friction dam per installa tion place
