[摘要] 深圳北站站房長(zhǎng)度超過(guò)400m，屬超長(zhǎng)大跨結(jié)構(gòu)。采用時(shí)程分析方法，考慮行波效應(yīng)，對(duì)站房進(jìn)行多維多點(diǎn)輸入時(shí)程地震反應(yīng)分析，主要分析重要構(gòu)件內(nèi)力，加速度響應(yīng)及扭轉(zhuǎn)位移比等，并與一致輸入進(jìn)行比較，同時(shí)考慮了不同波速的影響。最后對(duì)行波效應(yīng)不利影響較為明顯的構(gòu)件，設(shè)計(jì)采用反應(yīng)譜效應(yīng)放大1.3倍予以控制，適當(dāng)加強(qiáng)，確保了結(jié)構(gòu)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
