摘要
针对Revit自有的功能构建建筑信息模型(BIM)效率较低等问题,基于Revit二次开发,在没有桩基承台平面布置CAD图的情况下,通过识别由结构分析软件生成的柱(墙)底内力图的图元信息,提出了一种桩基承台自动设计算法。该方法以Revit制作单桩竖向承载力特征值计算表为基础,在C#中编写算法程序。根据桩基承台的构造和上部结构的要求自动设计出桩基承台,并将满足承载力要求的桩基承台准确地布置在相应的柱(墙)下,其显著地提高了桩基工程建模效率,且为后续工程量计算以及不同桩基础经济性比较提供便利。
The efficiency of constructing building information model by Revit is rather low.Based on Revit’s secondary development,in the absence of the CAD drawings of pile foundation caps,an automatic design algorithm for pile foundation cap is proposed by identifying the primitive information of the internal force diagram of the column (wall) generated by the structural analysis software.The method is based on the calculation of the eigenvalue calculation table of the vertical bearing capacity of the single pile in Revit.The algorithm program is written in C#.Then the pile foundation cap is automatically designed according to the requirements of the structure and the superstructure of the cap,and the pile caps satisfying the bearing capacity requirements are accurately arranged under the corresponding columns (walls),which significantly improves the efficiency of pile foundation engineering modeling,and facilitates the subsequent engineering calculations and economic comparison of different pile foundations.
