（鐵道第三勘察設(shè)計院集團(tuán)有限公司，天津 300251）[摘要] 對京滬線鐵路樞紐北京南站建立了整體模型，作了整體結(jié)構(gòu)分析計算。分析中主要考慮了恒載、風(fēng)荷載、溫度荷載、混凝土收縮、地震作用等等，對結(jié)構(gòu)自振特性、層間位移角等進(jìn)行分析計算，并采用了不同的軟件進(jìn)行計算、校核。結(jié)果表明：計算結(jié)果吻合較好，工程設(shè)計符合規(guī)范要求。由于北京南站在結(jié)構(gòu)形式上采用了創(chuàng)新性的“房橋合一”結(jié)構(gòu)體系，分析結(jié)果對設(shè)計有著較大的指導(dǎo)和參考意義。

( Third Railway Survey & Design Institute Group Corporation, Tianjin 300251, China)Abstract: The whole model of Beijing South Railway Station,a railway hub of Beijing-Shanghai line, was established and calculated in the whole structure. Based on the consideration of dead load, wind load, temperature load, contraction of the concrete, seismic action and so on, self-vibration characteristics and drift-angle between the layers were analyzed and calculated. Different software was used to calculate and check. It turns out that the analysis results are in good agreement, and the design of this construction meets design requirements and specifications. Because using the innovative frame-bridge combined system in Beijing South Railway Station, the analysis result has great guidance and reference significance to design.
