摘要

本研究旨在通过实验测试和分析建模来研究冷弯型钢螺纹连接的紧固旋转行为。试验和有限元结果均表明了倾斜和轴承的失效模式。采用具有螺旋板刚度的弹簧模型，包括螺旋的弯曲和剪切刚度以及螺旋和板的支承刚度，通过分析方法研究了螺旋连接的旋转失效模式。将螺纹直径、板厚和板厚比的变化分配给弹簧模型进行参数研究。螺钉的旋转或倾斜主要由板的厚度控制。结果表明，为了减少倾斜破坏的影响，螺钉的端部应嵌入冷弯型钢零件的最厚侧内。

Experimental and Theoretical Study on Screwed Connections in Cold-Formed Steel Structure

This research aims to study the fastening rotation behavior of cold-formed steel screw connections by experimental testing and analytical modelling. Both the experimental test and finite element results showed the failure modes of tilting and bearing failure. The rotation failure mode of the screw connection was studied by an analytical method using a spring model with screw-plate stiffness which included the bending and shear stiffness of the screw and the bearing stiffness of the screw and plates. Variation in the screw thread diameter, plate thickness, and plate thickness ratio are assigned to the spring model for the parametric study. The screw rotation or tilting was primarily controlled by the plate thickness. Presented results show that to decrease the effect of tilting failure, the end of the screw should be embedded within the thickest side of the cold-formed steel parts.

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
