超限高层框架结构采用粘滞消能减震支撑的抗震性能分析

Seismic analysis of irregular high-rise frame structure with viscous damping brace

针对采用粘滞消能减震支撑的超限高层框架结构抗震性能的复杂性,为了提高超限高层的抗震性能,对天津市某高校超限图书馆结构设计中结构选型、消能减震支撑的选择和布置进行反应谱和非线性时程的分析计算.分析结果表明消能减震支撑能有效地提高结构的抗震性能;粘滞阻尼器的数量不能决定消耗能量的多少,只有合理布置,才能更好地提高结构的抗震性能.

The seismic behavior of irregular high-rise structure with viscous damping brace is complex. In order to improve the seismic performance of high-rise building, the seismic response of response spectrum and nonlinear time-history analysis on an irregular college library in Tianjin of structure form selection, damper selection and layout is studied. The result show that viscous damping brace can effectively improve the seismic performance of structure; the number of viscous damper cannot determine how much energy consumption is, and only through the reasonable decorate, can it improve the seismic performance of the structure.
