在建筑信息模型(BIM,Building Information Model)技术基础上,通过研究其标准BIM文件格式IFC(Industry Foundation Class)标准,得到向IFC中性文件中扩展几何属性、混凝土材料属性数据和钢筋材料属性相关参数的方法,并通过C++编写的"数据整合模块"访问和分析处理IFC文件中的相关数据,生成供Fortran截面非线性程序读取的文件形式,进行非线性分析计算。最后将该方法应用到高性能钢纤维混凝土梁截面非线性分析实例分析中,分析结果与试验结果吻合较好,说明了所建议方法的合理性和适用性。
Based on building Information Model(BIM,Building Information Model),this paper introduced a method of adding related parameters such as material attribute and constitutive relation of concrete by the study of the standard file format of IFC(Industry Foundation Class).The"Data Integration Module"written by C++ could access and analyze the necessary data of IFC files,and then it generated the input file of section nonlinear analysis program. Finally,after comparing with the experiment results,the computational result of steel fiber reinforced concrete beam by the nonlinear program fits well.
