摘要

悬挂结构主要包括受压构件与受拉构件,受竖向荷载影响较大。将悬挂结构简化为考虑节点转动的串并联模型,通过计算得到结构的竖向刚度矩阵和相应的质量矩阵,并运用时程分析的方法,进行竖向地震作用下的动力反应分析,从中得出了悬挂结构竖向地震作用下的一些动力特性。最后,从结构可靠度等方面,对悬挂结构的设计提出了一些建议。
There are mostly pulled and pushed components in the suspended structure which almostly affected by vertical force.In this paper,the suspended structure has been simplified to the series-parallel-connection model which considered joint rotation.The vertical stiffness matrix and mass matrix have been obtained.There has been a dynamic characteristics analysis on the structure effected by vertical seismic force with the method of analysis of step-by step integer.From the result some dynamic characters of suspended structure under vertical seismic force have been obtained.At last,some advices about the design of suspended structure which from reliability degree of structure have been advanced in the paper.
