装配式轻钢混凝土板墙边节点设计及模拟分析

Design and Simulation of the Prefabricated Exterior Joint between Light Steel-Concrete Composite Slab and Walls

摘要: 本文提出了一种适用于装配式轻钢混凝土板墙体系的新型边节点形式，并对其进行了初步的有限元模拟分析。该新型节点采用自攻钉对轻钢混凝土预制墙板进行连接，而后再在节点区现浇混凝土。此种节点连接方式在浇筑混凝土之前就基本可以承载，因而可在本层装配完工后继续下一楼层的施工，在缩短施工周期方面具有很大优势。随后的有限元分析表明，该板墙节点的延性非常好，破坏形态为板端塑性铰破坏，符合抗震设计要求。综上，该节点形式设计合理，具有一定的研究和应用价值。

Abstract: This paper proposes a new kind of prefabricated exterior joint applicable for light steel-concrete composite panel structures, then conducts a preliminary finite element simulation analysis for it. Tapping screws are used to connect the prefabricated light steel-concrete composite walls and slab, and then concrete is casted into the joint area. The joint can basically bear loads before casting the concrete, so it’s practicable to assemble the next floor after assembling the former floor. So this joint has great advantage in shortening construction period. And the finite element analysis reveals that the joint’s ductility is very good and the failure mode is plastic hinge failure at the end of slab, so it meets requirements of aseismic design. To sum up, the joint is reasonably well designed and deserves further study and application.
