设置铅阻尼器的某常规岛主厂房耗能减震分析
|
摘要
铅阻尼器是一种滞回性能稳定、构造简单和受环境影响较小的耗能减震装置。为了研究铅阻尼器在常规岛主厂房中的耗能减震效果,本文采用非线性分析软件ABAQUS对设置铅阻尼器的某常规岛主厂房结构进行了罕遇地震作用下的有限元分析,对比不同地震波作用下的结构弹塑性分析结果。结果表明:设置铅阻尼器以后,结构的抗震性能显著提高,研究为铅阻尼器在常规岛主厂房结构中的应用提供了成功的工程案例,其设计思路可以为常规岛主厂房结构的减震提供有益的借鉴和参考。
The lead damper is a kind of energy dissipating device with stable hysteretic performance,good shock absorption performance and simple structure. To study of lead dampers damping effect in the main machine hall,the nonlinear finite element analysis software ABAQUS is adopted to analyze the seismic performance of a main machine hall in conventional island with lead dampers under the action of the different earthquake and compare the elastic- plastic analysis results under the action of different seismic wave in this paper. The results show the structural seismic performance has been improved significantly,a successful engineering case is provided for the application of lead dampers in the damping design of main machine hall structures.
