[摘要] 深圳北站站房长度超过400m，属超长大跨结构。采用时程分析方法，考虑行波效应，对站房进行多维多点输入时程地震反应分析，主要分析重要构件内力，加速度响应及扭转位移比等，并与一致输入进行比较，同时考虑了不同波速的影响。最后对行波效应不利影响较为明显的构件，设计采用反应谱效应放大1.3倍予以控制，适当加强，确保了结构良好的抗震性能。

Abstract：The length of station building of Shenzhen North Station was larger than 400m. It was belonged to ultra-long-span structure. Time-related method was adopted, and wave traveling effect was considered. Then seismic response analysis of station building floor system of Shenzhen North Station under multi-dimension and multi-support seismic excitation could be made. Compared with uniform excitation, some important components inner force, acceleration response and torsion displacement ratio could be analyzed. At the mean time, the effect of different wave speed was considered. At last, some wave traveling disadvantage effect obviously components were designed by 1.3 times of design response spectrum effect. Then they could to be controlled and strengthened suitability. Structural seismic performance was assumed to be favorable.
Keywords: Shenzhen North Station;multi-dimension and multi-support seismic excitation;wave traveling effect; effect factor
