[摘要] 对京沪线铁路枢纽北京南站建立了整体模型，作了整体结构分析计算。分析中主要考虑了恒载、风荷载、温度荷载、混凝土收缩、地震作用等等，对结构自振特性、层间位移角等进行分析计算，并采用了不同的软件进行计算、校核。结果表明：计算结果吻合较好，工程设计符合规范要求。由于北京南站在结构形式上采用了创新性的“房桥合一”结构体系，分析结果对设计有着较大的指导和参考意义。

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.
