西安某高层建筑动力特性及地震反应分析

应用Etabs软件,分析了西安市某拟建高层建筑的结构动力特性,确定了振型分解法的合理振型数量.通过非线性时程分析,得出该建筑结构在多遇地震和罕遇地震作用下的地震反应.最后确定出该高层建筑取前11阶振型作分析即能精确反应出结构的实际受力状态;并验算了该高层建筑在多遇地震作用下的最大水平位移和层间位移,结果均满足规范要求.

Analysis of the Dynamic Characteristics and Earthquake Response in One High Building of Xi'an

Construct the reinforced concrete shear wall in a high building of Xi′an,through using general analysis software Etabs,the building structure dynamic characteristics were analyzed to determine the number of the mode,as well as through the analysis of the non-linear time history,under the conditions of the buildings meeting the earthquake frequently and rarely,this structure earthquake response was obtained.Finally,the first 11 step mode of vibration regarding this high building was fixed to make the analysis to respohse precisely structure actual stressful condition,and under this high building meeting the earthquake frequently,its maximum horizontal displacements and the displacement between two stories were tested,these satisfies the code requirement.
