双塔连体结构动力特性分析

摘要

Citing one 16-floor symmetrical double-tower structure as examples, when the connected strustures are in different vertical positions, tridimensional analysis model is built according to ANSYS finite element analysis software. On the basis of it, the influence of connected strustures in different verticai positions on dynamic characteristics of the whole structures is analyzed. The change of vertical position of connected strustures has great influence on the vibrant characteristics, so it should be considered in the sructure design.%以某十六层双塔连体结构建筑为算例,运用 ANSYS 有限元分析软件,建立了连体位于不同竖向位置时的三维分析模型,对连体结构部分在竖向位置的变化对整体结构动力特性的影响进行了分析,连体竖向位置的变化对结构的振动特性影响较大,结构设计中应给予考虑.
