1 JOURNAL OF RAILWAY ENGINEERING SOCIETY Nov 2012 NO. 11 Ser ( 中信建筑设计研究总院有限公司, 武汉 ) 1 2 U24 A Comparison between Railway Codes and Building Codes in Design of Support Rail Structure QIU Jian YE Zhi - xiong WEN Si - qing XIE Xian - yi Citic General Institute of Architectural Design and Research Co. Ltd Wuhan Hubei China Abstract Research purposes Taking the support rail layer of the Guiyang North Railway Station as an illustration this paper comparatively analyzes the calculation result with the railway code and the calculaltion result with building code by the probabilistic limit states method and the permissible stresses method from the areas of the comparison of the calculation results with the typical software the control of the prestress degree of the prestressed beam and the control of the crack of the prestressed beam and discusses the design method for the structure of the support rail layer of the bridge combined with station building. Research conclusions 1 There is no essential conflict between the railway codes and building codes and the reasonable design of the framed support rail structure can be realized by appropriate control of the prestressing degree of the prestressed support rail beam according the railway codes and the building codes. 2 The calculation should be made according to the bridge codes for control of the crack of the framed support rail beam. Key words bridge combined with building support rail beam probabilistic limit states method permissible stress method prestressing degree
