BIM 技术在国内结构设计中应用的可行性分析

目前BIM 技术在我国结构设计方面的应用尚未得到推广，主要原因是结构物理模型与结构分析模型之间无法做到完美对接。结合上海某钢结构实际算例，应用常见的BIM 软件Revit Structure 与Robot Structural Analysis 进行双向链接分析，并将结果与PKPM 计算结果在重心、刚心位置、内力、周期以及层间位移等方面进行比较。计算结果表明，以Revit Structure 和Robot Structural Analysis 结合进行分析的BIM 技术基本适用国内的结构设计和构件验算，但不适用于抗震等方面的验算。最后应用RStar CAD 将Revit Structure 与PKPM 进行链接，并评析其特点，为BIM 在我国结构设计中的应用提供参考。

Feasibility Analysis of BIM Application for Chinese Structural Design

Currently the application of BIM technology on structural design has not spread in China，and one of key reasons is the linking problems that physical models and analytical models cannot match perfectly. Revit structure and robot structural analysis are used to analyze a particular steel structure in Shanghai，and compare the differences with the results of PKPM in mass and rigidity centers，forces，periods and inter-story displacements. It shows that BIM technology linking revit structure and robot structural analysis can be utilized to check structural design and component strength，but cannot be applied to checking other aspects such as anti-seismic capacity. Finally，the methods and features of linking revit structure and PKPM by RStar CAD are discussed to provide suggestions for the structural design.
