粘滞阻尼器在某小学减震设计中的应用
|
摘要
通过对云南地震高烈度区某小学综合楼进行了消能减震设计,介绍了减震设计思路和原则,采用粘滞流体阻尼器的减震设计方案,对结构进行了非线性时程分析。分析结果表明,减震结构在多遇地震作用下楼层剪力,层间位移角较减震前均有明显的减小,且位移角满足《建筑抗震设计规范》限值要求,在罕遇地震作用下塑性发展较好,大部分梁出铰,柱少数出铰,满足规范"强柱弱梁"的破坏机制,表现出良好的抗震性能,且有很好的安全储备。
Through energy dissipation damping design for a primary school building in the high earthquake intensity area in Yunnan province,the design thinking and principle of damping are introduces,the structure with viscous flow of dampers are analyzed by nonlinear time history. The analysis results show that the story shear and drift decrease of damping structure under the frequent earthquake,and the story drift meets"Code for Seismic Design of Buildings",the plastic development is good under rare earthquake,most of the beams come out of the hinge,a few column come out of the hinge. It meets"strong column weak beam"failure mechanism,shows good seismic performance,and has higher safety reserves.
