[摘要] 深圳北站站房長度超過400m，屬超長大跨結構。采用時程分析方法，考慮行波效應，對站房進行多維多點輸入時程地震反應分析，主要分析重要構件內(nèi)力，加速度響應及扭轉位移比等，并與一致輸入進行比較，同時考慮了不同波速的影響。最后對行波效應不利影響較為明顯的構件，設計采用反應譜效應放大1.3倍予以控制，適當加強，確保了結構良好的抗震性能。

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
