摘要
大底盘非对称塔楼是一种复杂的结构体系,结构的上下刚度变化很大。采用三维有限元分析软件对一组上下刚度比值不同的非对称塔楼结构模型进行分析,计算表明,底盘与塔楼刚度比值β变化对结构各振型的振动模式影响不大,当β值取为3时,结构的周期和整体位移均达最小值。
The unsymmetrical tower with enlarged base is a kind of complicated structure system and its stiffness varies remarkably with the parts of the structure. The analysis and calculation of a series of models with varying stiffness ratio using finite element analysis software suggest that the vibration modes of structure change little when
