在桥梁设计专业软件中纳入桥规理念

Introduction of Philosophy in Bridge Design Codes into Professional Bridge Design Software

我国桥梁建设事业发展迅速,公路和铁路桥梁设计规范的理念和计算方法都有了改进,在规范和有限元理论发展的基础上,桥梁设计专业软件中需要纳入新的桥规理念,在对其中的编程语言、内力分项、效应组合、理论模型的建立、桥梁钢结构规范的实现、后处理关键技术难题进行分析后,编制的"桥梁结构设计系统软件"已基本吸纳了《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62-2004)、《铁路桥涵钢筋混凝土和预应力混凝土结构设计规范》(TB 10002.3-2005)及《铁路桥梁钢结构设计规范》(TB 10002.2-2005),该软件已成功运用于实际工程,实施效果好。

The bridge construction in China has gained a rapid development and both the philosophy and calculation methods in the design codes of highway bridges and railway bridges have made a significant improvement.Along with the progress of the codes and finite element theory,the new philosophy in the codes are necessarily to be introduced into the professional bridge design software.On the basis of analysis of the critical technical problems like the programming language,internal force dividing,effect combination,theoretic model establishment,steel structure code application and the relevant post-treatment,the newly programmed ＂Systematic Software for Bridge Structure Design＂ almost includes all the new philosophy in the Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts（JTG D62-2004）,the Code for Design on Reinforced and Prestressed Concrete Structure of Railway Bridge and Culvert（TB10002.3-2005） and the Code for Design on Steel Structure of Railway Bridge（TB10002.2-2005）.The systematic software as mentioned has already been successfully applied to actual bridge projects and the effect of application of the software is sound.
