应用振型分解反应谱法和时程分析法对某正交空腹网壳结构进行常遇地震作用下的抗震分析。讨论在不同方向、不同维数地震波激励下正交空腹网壳结构的动内力分布特点。分析结果表明,计算结构地震响应时需按多向多维进行分析,振型分解反应谱法与时程分析法计算的轴力动内力系数基本一致,而弯矩动内力系数差别较大。
Seismic analysis of a kind of orthogonal fast reticulated shell subjected to frequent earthquakes using mode decomposition decomposition time history method and time - history analysis method. The dynamic internal force distribution of orthogonal fast reticulated shells excited by seismic waves of different dimensions and different dimensions is discussed. The analysis results show that it is necessary to analyze multi-directional and multidimensional seismic response in structural calculation. The axial force dynamic internal force coefficient calculated by modal decomposition response spectrum method and time-history analysis method is basically the same, while the dynamic internal force coefficient differs greatly.
