［摘要］采用橋建合一形式的鐵路客站框架承軌結(jié)構(gòu)，其承軌梁一般有普通混凝土梁和預(yù)應(yīng)力混凝土梁兩種。分析比較鐵路橋梁和建筑結(jié)構(gòu)的異同點(diǎn)，對框架承軌結(jié)構(gòu)的兩種方案進(jìn)行靜力彈塑性分析，比較兩種方案的抗震性能，結(jié)果表明，兩種方案都具有很好的抗震性能，均能滿足抗震設(shè)計(jì)規(guī)范的要求。比較兩種方案的裂縫、長期徐變撓度、動撓度等計(jì)算結(jié)果。最后指出，預(yù)應(yīng)力混凝土梁具有更好的抗裂和抗疲勞性能。

Abstract: The rail-bearing beams of framework rail-bearing structure in railway station, which adopts the form of bridge-station combined structure, have two kinds of beams, including the ordinary concrete and prestressed concrete beam. The similarities and differences between railway bridge and building structure were compared, and two schemes of framework bearing rail structure were analyzed by Pushover. The seismic performance of two schemes was compared. The results show that the two schemes have good seismic performance, and can meet the requirements of the seismic design code. Then the crack, long term creep deflection and dynamic deflection of two schemes were compared too. Finally, it is pointed out that the prestressed concrete beams have the better resistance to cracking and fatigue performance.

Keywords: bridg-station combined structure; frame support rail; prestressed concrete beam; Pushover; seismic performance
