多层框架结构基础隔震有限元分析
|
摘要
以一幢8层框架结构的隔震建筑和传统抗震设计建筑的抗震效果进行分析对比,应用ABUQUS软件建立框架计算模型,分别采用普通叠层橡胶支座(RB)和铅芯橡胶支座(LRB)作为隔震装置的基础隔震2种隔震抗震方案,对其框架结构模型的底部输入E-l centro形地震波.分析结果表明,RB方案与LRB方案的抗震效果均优于传统方案,且RB方案抗震效果略好于LRB方案.
The latest building seismic design code includes the isolation structure design.The further research on the base isolation standardization process of building structure becomes the development trend of the future building seismic design.In this paper,time-history analysis method was used to analyze the multilayer frame isolation building in the earthquake under the action of seismic effect.We analyzed and compared seismic effects for both the actual isolated building of eight-layer frame structure and the traditional seismic building,and established the framework computing model by ABUQUS software.The ordinary laminated rubber bearing(RB) and lead core rubber bearings(LRB) were taken respectively as the basic seismic isolation scheme and then El-centro seismic wave was imported into the bottom of the frame structure model.The analytical results about seismic performance show that both RB and LRB schemes are superior to traditional scheme and RB scheme is slightly better than LRB.
