(西南科技大学土木工程与建筑学院,绵阳 621010)[摘要]讨论分析了高层建筑结构在非线性地震反应时程分析中,设置粘弹性阻尼器的优化问题,经正多面体法进行优化处理后,所使用的粘弹性阻尼器只有原来的1/5~1/2,大大节省了粘弹性材料的使用,降低了成本,产生了较大的经济效益。[关键词]非线性地震反应;时程分析;粘弹性阻尼器;高层建筑结构Optimizing on viscoelastic damper in concern with time history analysis of reaction to non-linear earthquakeZhao Mingbo(Southwest University of Science and Technology,Mianyang 621010,China)Abstract:It discusses and analyzes the optimizing of viscoelastic damper in concern with the time history analysis of high-rise frame′s reaction to non-linear earthquake. Optimized with the regular polyhedron method, the viscoelastic damper is only 1/5 to 1/2 of the original in size, which saves the viscoelastic material and as a result, lowers the cost.Keywords:reaction to non-linear earthquake; time history analysis; viscoelastic damper; high-rise frame*国家自然科学基金项目(59678046)。作者简介:赵明波,讲师,Emial:zwave@126.com
