摘要

对某单跨飞机库采用振型分解反应谱法进行了考虑多向输入的地震反应分析,沿结构单向、双向和三向输入的不同情况,从结构柱列内力和屋盖杆件内力等方面进行了比较和分析,分析结果表明:与单向地震作用相比,考虑多向地震作用后,结构柱列的次方向内力增幅显著,三向输入的影响应该考虑。
The paper undertakes the seismic response analysis of multi-way input by adopting the mode-superposition response spectrum in some single-span hangar,compares and analyzes the structural columns from the column internal force,and the internal forces of rod according to the various circumstances of the structural one-way input,the double-way input and the three-way input,and proves by the analysis results that the secondary internal force are increased obviously by comparing with the one-direction seismic impact and considering the multi-direction seismic effect,and the influence of the three-direction input should be considered.
