摘要
高层结构施工规模巨大,施工周期长,在施工过程中仍有一定概率经要受地震作用的考验。利用大型有限元软件ABAQUS建立了广州财富中心施工各阶段的有限元模型,采用时程分析方法对广州财富中心各施工阶段的未完工结构在多遇地震和施工荷载组合作用下的抗震承载力和结构变形进行了分析,验证了结构在施工过程中的安全性。还对不同地震波作用下结构的振动响应进行了对比分析,结果表明:结构的地震响应受地震波卓越频率的影响十分明显,超高层结构在低频长周期地震波作用下的响应明显大于高频地震波作用下的响应。
High-rise buildings are of large construction scale and long construction period. The may be damaged by earthquakes during construction with some probability. The finite element models of Guangzhou Wealthy Center in different construction stages were constructed by ABAQUS. The aseismic bearing capacity and deformation of the constructing structures under frequent earthquake action and construction loads were analyzed, and the safety of the structure during construction was also verified. Moreover, the comparison results of the responses under different earthquake waves indicated that it depended on the predominant frequency. The response of high-rise building under low frequency and long period earthquake waves were apparently hither than that of under high freauencv earthquake waves.
