桥梁BIM与有限元软件二次开发接口制作及其应用
摘要：结合半穿式连续钢桁架桥，基于Autodesk Revit建立初始模型。然后调动Revit软件API，对其进行软件的二次开发，做出接口使模型几何参数和材料参数赋值输出为ANSYS APDL命令流文件。通过ANSYS对关键节点进行受力特性分析，对连接部分进行优化处理，并反馈给初始模型。利用信息化模型与有限元软件结合对该桥的关键节点进行了细化设计与分析，从而论述了在BIM体系下对桥梁局部节点受力优化的意义。

Design and Application of Secondary Development Interface of BIM Model and Finite Element Analysis Software of Bridge
Abstract: Based on a half-through continuous steel truss bridge,Initial model building was created by Autodesk Revit. By using REVIT software API,the secondary development of the software was carried out,and the interface was made so that the model geometric parameters and material parameters were assigned and output as ANSYS APDL command flow file. The finite element software was used to analyze the stress characteristics of the key nodes,optimize the connecting parts,and feed back to the initial model. In this paper,the key nodes of the bridge were designed and analyzed in detail with the combination of information model and limit element software,so as to discuss the significance of force optimization for local nodes of the bridge under the BIM system.
Keywords: bridges; continuous steel truss bridges; paperless design; finite element analysis; building information modeling(BIM); BIM secondary development
