| 摘 要： | 对7度抗震设防和Ⅳ类场地条件的某大跨度飞机库进行了罕遇地震下多维地震输入的弹塑性时程反应分析,采用直接积分的动力分析方法,选用3条地震波分别计算了三向输入和单向输入下结构的地震反应.通过对比,研究结构在多维强震作用下的受力变形性能.分析表明,与单向水平地震作用相比,多维地震输入下结构下部支承柱柱底塑性铰数量总体上有所增加,部分塑性铰发展程度加深;最大柱顶侧移及柱底内力总体上有一定增加,但增幅较小;屋盖结构受多维地震作用的影响较大,塑性铰数量及杆件地震内力都明显增加. |

| Abstract: | Elasto-plastic response time-history analyses of a long-span hangar based on site-class Ⅳ were performed under 3 seismic inputs of rare major earthquake for the seismic fortification intensity of 7,using direct integration method.Dynamic responses of the structure subjected to one-dimensional and three-dimensional earthquake inputs were compared.The results show that,with three multi-dimensional earthquake inputs,more plastic hinges of its supporting columns appeared,and for some of them,the plastic damage got worse;The maximum lateral displacements of the structure and the maximum internal forces of its columns are increased slightly;whereas,the roof structure were influenced more obviously,the number of hinges and internal forces of roof members got significantly increased. |
