装配式钢结构体系中预制外墙板多采用外挂的方式与主体结构连接,其连接节点既要保证外挂墙板的安全可靠,还要保证外挂墙板与主体结构之间的变形协调。提出一种构造简单、施工方便的新型装配式钢结构外挂墙板连接节点,并给出该节点的设计以及验算方法。以某工程为例进行节点验算和有限元分析,并对其承载力进行参数化研究,揭示节点的传力机制以及破坏形态,结果表明该节点具有良好的受力性能和应用前景。
The precast cladding wall panels are generally connected to assembled steel structure with out-hung connection which should not only ensure the safety and reliability of the cladding panels but also keep the deformation consistent between the cladding panels and the structures. A new out-hang connection of assembled steel structure cladding wall panels characterizing simple structure and easy construction was presented, and the design and detailed capacity checking method were suggested. An project case was provided to conduct connection calculation and finite element analysis, and the parametric study was conducted for bearing capacity of connection to investigate its force transfer mechanism and failure model. The results show that this new connection has good mechanical behaviors and application potential.
