Abstract This paper presents the details and application of a newly developed variably oriented spring pair element (VOSPE) model and the Bouc-wen-Baber-Noori (BWBN) constitutive model, to represent the behaviour of the screw connections between the CFS framing and the sheathing in the non-linear finite element analysis of the cold formed steel shear wall panels (CFSSWP) under the monotonic and cyclic loadings. The parameters of the BWBN model were obtained from the experimental load-displacement behaviour of the screw connection data, with the screw experiencing shear parallel to the free edge of the sheathing. The proposed VOSPE screw model was implemented in ABAQUS to analyse the behaviour of cold formed steel wall panels. The finite element analysis results compare well with the experimental results of the overall wall panels under both the monotonic and cyclic loadings, wherein the behaviour and the strength were essentially dictated by the non-linear behaviour and strength of the screw connections. Finally, a non-linear dynamic analysis of a wall panel under an earthquake loading is illustrated, using the proposed model of the wall panel.

CFS剪力墙板新的螺纹连接模型和有限元分析

摘要 本文介绍了新开发的可变定向弹簧副单元 (VOSPE) 模型和 Bouc-wen-Baber-Noori (BWBN) 本构模型的细节和应用，以表示 CFS 框架和框架之间的螺纹连接的行为。冷成型钢剪力墙板 (CFSSWP) 在单调和循环载荷下的非线性有限元分析中的护套。BWBN 模型的参数从螺钉连接数据的实验载荷-位移行为中获得，螺钉经历平行于护套自由边缘的剪切。建议的 VOSPE 螺杆模型在 ABAQUS 中实现，以分析冷成型钢墙板的行为。有限元分析结果与整体墙板在单调和循环载荷下的实验结果相比很好，其中行为和强度基本上由螺纹连接的非线性行为和强度决定。最后，使用建议的墙板模型说明了在地震荷载作用下墙板的非线性动力分析。
