盛德大厦改建工程抗震性能研究
|
摘要
针对广州盛德大厦改建设计后的结构进行抗震性能研究。要求改建设计后的结构满足现行结构规范,故对原已建部分承载力复核并采取相应的加强改造措施,以确保其有足够的抗震能力。改建后的结构设计采用基于性能的抗震设计方法,包括小震弹性计算、中震弹性以及中震不屈服构件验算,以及罕遇地震下的弹塑性分析。利用ETABS和PERFORM-3D分析软件进行了整体结构弹性及弹塑性时程分析和推覆分析,并运用多种分析手段验证不同地震作用下结构的抗震性能,最后校核了桩基础在地震作用下的承载力。
The seismic performance research of the reconstructing design structure of Shengde building was presented.As the reconstructing design structure is required to meet the demands of current code,the bearing capacity of the original part was checked and some improving and strengthening measures,which ensure the structure have enough seismic capacity,have been taken.Design and analysis procedures of the reconstructing design structure,which are based on the performance-based seismic design method,consist of elastic analysis under frequent earthquake,elastic analysis and un-yield analysis of components under moderate earthquake,and elastio-plasticity analysis under rare earthquake.Analysis of the whole structure model including elastic time history analysis,elastio-plastic time history analysis and pushover analysis were applied by ETABS and PERFORM-3D software.Different seismic performance levels of the whole structure were checked by different analysis methods.In the end,the bearing capacity of pile foundation under earthquake was verified in order to meet the demand of current code.
