摘　　要：为解决BIM模型向有限元模型信息转换的局限性,提出了基于APDL语言的二次开发转换模型信息的思路;从软件底层数据角度进行分析,对BIM模型信息进行提取及转换;通过对几何图形类型的派生关系进行分析,完成了提取和转换算法的编写;通过对有限元信息转换程序研发,实现BIM模型向有限元模型全自动信息转换,从而完成仿真模拟计算,满足桥梁工程设计计算的要求,解决了重复性建模问题,为桥梁一体化设计提供支持。In order to solve the limitation of converting BIM model to finite element model information,the idea of converting model information through secondary development is proposed based on APDL language;analysis is conducted from the perspective of the underlying software data to extract and convert BIM model information;by analyzing the derivation relation of geometry type,the algorithm of extraction and conversion is completed;through the development of the finite element information conversion program,the automatic information conversion from the BIM model to the finite element model is realized,so as to complete the simulation calculation and meet the bridge engineering design calculation,which solves the repetitive modeling problem and provides support for the integrated design of bridges.
