空间结构──设备体系模型分析
|
摘要
本文根据实际工程背景及对国内外文献综述［１］，建立了空间结构──设备体系地震反应分析模型，并采用杆系有限元方法，推导出该模型在双向水平地震动输入下的无阻尼系统的运动方程。考虑到结构系统和设备系统之间材料的差别，瑞利阻尼假定不适用，采用了一种新的组集结构──设备体系阻尼矩阵的方法，该方法与结构──设备体系的振动台实验结果相比较，结果令人满意。
In terms of the actual engineering projects background and literary summarization homeand abroad, the paper establishes the space model of the earthquake response analysis of combined st ructure-equipment system. By using of the finite elernentm ethod, t h e d yn amic equations of non--damping system on the two--dimensional level input are derived as well. Considering the materal difference between the structure system and equipment system, the ritydamping hypothesis can't be used any more, a new assembling method of damping matrix isproposed. Finally,the program for the computer analysis of the coupled system is developed.Compared with the results of the shaking table test,the results are satisfactory.
