摘要
为了解决实际工程中进行有限元计算时存在的建模时间长、建模难度较大及建模精度不足等问题,将BIM软件Revit与有限元软件相结合,在Revit中完成某钢筋混凝土厂房的三维建模,然后导出有限元软件接口文件,在有限元软件中进行模型的网格划分与计算,从而实现了BIM技术与有限元技术的相结合。对于厂房类框架结构,在Revit软件中易于实现建模与配筋,利用其建立的模型对结构进行有限元计算能显著提高工作效率且能提高计算结果的准确性。
The purpose of this paper is to solve the problems existing in finite element calculation in practical engineering,such as long modeling time,great difficulty in modeling and inadequate modeling accuracy.This paper combines BIM software Revit with finite element software to complete three-dimensional modeling of a reinforced concrete building in Revit.Then the interface file of finite element software is derived and the meshing and calculation of the model are carried out in the finite element software,which realizes the combination of BIM technology and finite element technology.For the frame structure of plant type,it is easy to realize modeling and reinforcement in Revit software.Using the model established by Revit to carry out finite element calculation on the structure can significantly improve work efficiency and accuracy of calculation results.
