【摘要】 采用ANSYS通用有限元程序建立了巨型框架结构隔震分析的动力计算模型,对巨型框架结构进行了隔震动力时程计算,给出了巨型框架结构隔震后在多条地震波作用下的动力位移及内力等地震响应。计算结果表明,巨型框架结构在隔震后具有良好的抗震性能,可有效地降低结构的地震响应,计算结果对于确保巨型框架结构的抗震安全性具有较大的意义,同时对选择结构构件截面尺寸,也具有较大的参考价值。更多还原

【Abstract】 The ANSYS finite element program was used to analyze the earthquake isolation to the mega-frame,and it was discussed the mega-frame system′s displacement responses,such as dynamical displacement,internal force response,etc.It shows that mega-frame construction with seismic isolation has good earthquake resistance performance,reduced the structure earthquake response.This result has more practical significance to the structural safety.This is in concert with the section size choice of a structure,so it is practical.更多还原
