Step-by-step Integral Analysis of Suspended Structure Effected by Vertical and Horizontal Seismic Force
【摘要】 本文对悬挂结构建立了考虑节点转角影响的串并联质点模型,建立结构自由振动的微分方程,采用静力凝聚法消去主副自由度之间的耦合关系,得到考虑水平和竖向耦合自由振动的频率,运用时程分析法对结构进行了动力响应计算,分析了耦合影响,为该领域进一步的研究提供参考。
【Abstract】 A series-parallel-connection model with considering the influence of rotation nodes is developed in this paper. The coupling of horizontal and vertical displacement and the rotational displacement are eliminated using static condensation method. The frequency of free vibration, which couples with the horizontal and vertical vibration, is also given. The structure dynamic response subjected to both horizontal and vertical seismic excitation is obtained by using step by step integral method, which is of benefit to further research of the field.
