【摘要】：青岛胶东国际机场航站楼平面长达1 090m,结构设计应考虑非一致地震激励的影响。航站楼大厅结构行波效应分析表明,网架杆件的轴力行波效应较小;底层框架柱内力行波效应最大,行波效应系数的分布范围较广,随着楼层增加逐渐减小;大多数柱的内力均小于一致激励的结果,超载柱的行波效应系数多集中于1.0~1.25区间;结构尽端、分缝处、平面开大洞区域边界的行波效应显著;结构平面变窄的区域,其尽端框架柱行波效应显著,其承载力和延性应有针对性的提高。
[Abstract]:The plane of the terminal building of Qingdao Jiaodong International Airport is 1090m, and the influence of non-uniform seismic excitation should be considered in the structural design. The analysis of traveling wave effect of terminal hall structure shows that the axial force traveling wave effect of space truss member is small, the inner force traveling wave effect of bottom frame column is the largest, the distribution range of traveling wave effect coefficient is wider, and the traveling wave effect coefficient decreases gradually with the increase of floor. The internal force of most columns is less than the result of consistent excitation, the traveling wave effect coefficient of the overload column is mostly concentrated in the range of 1.0 ~ 1.25, and the traveling wave effect is obvious at the end of the structure, at the joint, and at the boundary of the area with a large hole in the plane. When the structure plane becomes narrow, the traveling wave effect of the end frame column is obvious, and its bearing capacity and ductility should be improved.
