装配式钢混组合主次结构设计要点与分析

DESIGN KEY POINTS AND ANALYSIS OF PREFABRICATED STEEL-CONCRETE COMPOSITE PRIMARY AND SECONDARY STRUCTURE

为了总结装配式钢混组合主次结构体系在EPC全过程中的设计方法,对示范工程的设计概况、设计方法和BIM的应用,设计在研发、商务、生产、施工等建造全过程中的问题及解决方法进行了详细阐述。结果表明:本体系完成了与减震技术的有效融合;结构设计要关注主结构和次结构的相对关系、受力模式、构件选型、节点做法、预制构件;在建造各阶段应注意各专业、全过程协同。

This paper elaborates the project overview,design method,applied BIM and problem and countermeasure of design over the whole process of demonstration EPC project in order to summarized structural design theory of the prefabricated steel-concrete primary and secondary composite structure system.The result shows that:this system has completed the effective combination with energy dissipation technology.The main points of structural design are the relationship between the primary structure and the secondary structure,the pattern of stress,the method of joints,and the selection of components and prefabricated units.Structural designer should pay attention to enhance the collaboration with other professions in every stage of the project.
