旅客登机桥作为连接飞机与航站楼的通道,桥体各结构部件之间的约束是非完全的,在某些方向上应视为可动体系,由于桥体在行进过程中需同时实现旋转与伸缩,桥体各部分之间的连接方式有滑动和转动,结构动态响应特性有别于一般桥梁。采用弹性时程分析法,考虑通道间的耦合影响和液压支腿底部滚轮与地面间的非线性摩擦接触,进行多遇地震激励下的结构抗震性能分析,对登机桥结构有效承载力做了定量研究。结果表明,地震激励的影响主要集中于底部基础构件,以水平方向激励的破坏尤为巨大,因而在对底部基础螺栓进行设计校核时,地震激励的影响不容忽视,并且还应该以地震激励下结构的动力响应作为设计校核的准则。
Passenger boarding bridge as a connection between the aircraft and the terminal building, the bridge between the various structural components of the constraint is incomplete, in some directions should be considered as a movable system, due to the bridge in the process of traveling at the same time to achieve rotation With the telescopic, the bridge between the various parts of the connection between the sliding and rotation, the dynamic response of the structure is different from the average bridge. By using the elastic time-history method, considering the influence of coupling between channels and the non-linear friction contact between the roller at the bottom of the hydraulic leg and the ground, the seismic performance of the structure subjected to the earthquake excitation is analyzed, and the effective bearing capacity of the boarding bridge is made Quantitative Study. The results show that the influence of seismic excitation is mainly concentrated on the bottom of the basic components, especially in the horizontal direction. Therefore, the influence of earthquake excitation can not be neglected when designing and checking the bottom foundation bolts, and the seismic excitation structure Dynamic response as a design check criteria.
