摘要:为了解决钢筋混凝土结构梁柱节点处由于钢筋密集交错、形式复杂多样而造成的节点设计深度不足的问题，依据梁柱节点处钢筋锚固与排布的规范要求，结合设计及建造经验，建立了基于Revit族的梁柱节点全三维参数化设计模型，实现了梁柱节点三维可视化设计，该方法不仅能够快速生成典型节点钢筋模型，而且可以从三维的角度进行钢筋避让的交互操作，解决了节点处钢筋碰撞和锚固不足的问题; 运用Revit API和C#编码读取项目中梁柱节点的节点类型，调取已建立的节点三维参数化模型，然后载入项目节点框架中实现节点钢筋三维模型的自动生成并在实际工程中进行验证，本文提出的设计方法可行高效，研究为钢筋混凝土结构节点部位钢筋的深化设计提供了基于BIM技术的解决方案。

Abstract: In order to solve the problem of insufficient depth of joint design at the beam-column joint of reinforced concrete structure due to the intensive staggered reinforcement and complex forms, according to the specification requirements of reinforcement anchoring and arrangement at the beam column joint, combined with the design and construction experience, a full 3D parametric design model of beam column joint based on Revit family is established, and the 3D visual design of beam column joint is realized. This method can not only quickly generate the typical joint reinforcement model, but also carry out the interactive operation of reinforcement avoidance from the perspective of three-dimensional, so as to solve the problem of insufficient reinforcement collision and anchorage at the joint. Using Revit API and C# code to read the joint types of beam column nodes in the project, adjust the established joint three-dimensional parametric model and load it into the joint frame to realize the fast joint reinforcement. The application of the project shows that the proposed method is feasible, and provides a BIM based solution for the in-depth design of the joint reinforcement.
