高层钢框架粘弹性阻尼器隅撑支撑结构抗震性能分析

 摘要：本文在构建钢框架结构体系的基础上采用了三种粘弹性阻尼器隅撑支撑布置方案，通过运用有限元分析软件SAP2000进行水平地震作用下的弹塑性时程分析，说明结构动力特性和地震响应两个方面的计算成果。结果表明，设置粘弹性阻尼器隅撑支撑对结构自振周期影响不明显，但对顶层最大位移和基底剪力的控制效果非常明显。

Analysis on Earthquake Resistant Performances of Corner Support Structure for Viscoelastic Damper of High Building Steel Frame

Abstract: Based on truss structure system, three programs of knee braced structure with viscoelastic dampers is adopted and analyzed by elastoplastic seismic time-history analysis with using finite element analysis software SAP2000 and the two calculate achievement of dynamic characteristics analysis and seismic response is specified.The consequence indicate that the natural vibration period of knee braced structure with VED change unconspicuously,but the regulation of top floor’s maximum displacement and base shear is conspicuous.
