【摘要】 针对拱形屋盖结构，考虑空间作用的影响，采用大规模参数化分析的研究方法，利用国际上通用的有限元分析程序SAP91，应用振型分解反应谱法，在水平和垂直地展作用共同作用时，考虑常用范围内不同跨度、高度、长度、荷载大小、及其它一些地震参数的影响，获得拱形屋盖结构的地震反应特征及地震内力系数，和一些对工程设计有益的结论，同时还考虑了振型截取问题。更多还原

【Abstract】 This paper acquires earthquake response characteristics and seismic coeffcients of the arch roof, taking in account the influence of space functions by means of the Inrge Scale -Parameter Analysis approach, response spectrum theory and the very popular finite - element program SAP91.Meanwhile the horizontal and vertical earthquake motions are considered. According to different span,height, length, load and some other influences of earthquake parameters, useful results and some conclusions benefited to engineering designs are produced. And also the problem of vibration shapes cutting has been considered.更多还原
