BIM技术在桥梁加固中的力学分析应用

Application of BIM Technology in Mechanical Analysis of Bridge Reinforcement

BIM(建筑信息模型)应用是未来设计的方向,但目前通过BIM建模进行有限元分析的相关研究较少。将BIM设计软件Revit和传统有限元软件AnsysWorkbench结合起来,对已有的拱桥采用BIM建模进行加固计算分析。选用了主拱圈增设拱肋和套拱两种增大截面加固方案,分别采用有限元软件和BIM建立计算模型,并将两种计算模型计算的加固前后结果进行了对比,验证了Revit和AnsysWorkbench交互的可行性,可为BIM的有限元分析过程起到借鉴作用。

Application of BIM(Building Information Modeling)is the future way of designing,however,there are few studies on mechanical analysis through BIM. BIM designing software and traditional finite element software are combined,and BIM modeling is used for reinforcement calculation and analysis of existing arch Bridges. Two strengthening schemes of increasing the section of main arch ring,arch rib and cover arch,are selected,and the finite element software and BIM are used to establish the calculative model respectively. The results of the two calculative models before and after reinforcement are compared to verify the feasibility of Revit and Ansys Workbench interaction. It can be used for reference in the mechanical analysis of BIM.
