【摘要】 为比较在5.12汶川地震和东日本大地震作用下高层结构时程响应的差异,分别从这两次地震记录库中挑选出典型场地地震动加速度记录各3条作为结构输入地震动,采用ANSYS软件建立一88层高层建筑结构三维有限元分析模型进行时程响应分析.结果表明,在东日本大地震强震记录作用下高层结构的位移反应、加速度反应以及基底剪力和弯矩值,均明显大于5.12汶川地震动记录作用的结果.更多还原

【Abstract】 To compare the different seismic responses of the high-rise building under 5. 12 Wenchuan Earthquake and the East Japan Earthquake,6 acceleration records from earthquakes in typical sites were selected from the databases of the two earthquakes as input records. Then,a high-rise building 3D model was established using the finite element analysis software to do the time-history responses analysis. The results show that the displacement response,acceleration response,base shear force and the base bending moment of the high-rise structure under the East Japan strong motion records are significantly greater than that under the 5. 12 Wenchuan strong motion records.更多还原
