摘要

结合《建筑抗震设计规范》(GB50011-2001),在隔震结构初步设计阶段,运用迭代的思路对某8层框架基础隔震结构进行了简化估算.并与有限元通用软件ANSYS时程分析结果进行了比较,结果显示:多遇地震下上部结构总水平地震作用、罕遇地震下隔震层水平剪力和位移与时程分析结果得到了较好的一致.这将改变以往决策过程中完全凭借经验的盲目性,使得设计人员在实际的设计过程中能更好地把握设计要求,有利于提高设计质量.
Based on the Code for Seismic Design of Buildings(GB50011-2001),iteration is used to simplify an eight-story frame base-isolated structure in the preliminary design stage of the isolated structure.The results are compared with those with the time-history analysis of finite element software ANSYS.The results show that: the overall level seismic action of the upper part under frequent earthquakes and the shearing force and displacement of the isolation layer under rare earthquakes conform well to the results of time-history analysis.It will overcome blindness of former decision-making process relying on experience completely and enable the designers to grasp the design requirements well in the actual design process.It is beneficial to improving the design quality.
