| 摘 要： | 首先采用反应谱法和时程分析两种方法对大跨度空间网壳结构进行了全面分析,了解该形式结构的工程抗震受力性能。然后对两种方法的分析结果进行了对比,考查了结构杆件内力的变化,进而得出了内力差异随结构跨度、矢跨比和周期等的变化关系,找出了采用球反应谱法分析得出的结构响应偏于危险的杆件,从而为网壳结构的抗震设计提出了改进建议。

| Abstract: | The comprehensive analysis of long span space reticulate shells was carried out through the response spectrum method and the time history response method.Then,the results got from the two methods were compared,the differences of internal force in elements were checked and the variation of the differences of internal force with structure span,the ratio of height and span and period were presented.The dangerous elements which are got by the response spectrum method are found to give some suggestion in the imp... |
