单剪螺栓连接的冷弯薄壁板的荷载-变形曲线

给出了单剪螺栓连接的冷弯薄壁板的试验、数值和分析研究结果。共进行了18组试验,给出了的荷载-变形曲线和荷载-应变曲线的详细数据,以验证有限元模型。被证实了的有限元模型可进行全面的参数研究,用于得出不同的设计参数对连接板性能的影响,这些设计参数包括初始刚度、极限承载力和极限状态下的变形。结果表明,采用现行方法可以准确地预测板的刚度和极限承载力。然后,分析研究集中在得出一个计算极限状态下板最大的变形(孔洞的变形率)的方法。基于参数研究的结果,提出了不同的连接破坏模式下极限变形的计算方法。

Load-Deflection Behaviour of Thin-Walled Plates with a Single Bolt in Shearing

This paper presents an experimental,numerical and analytical study of the behaviour of thin-walled plates connected by a single bolt under shear.Eighteen tests were carried out to provide detailed data of load-deflection and load-strain curves for validation of the finite element simulation model.The validated finite element model was then used to perform a comprehensive set of parametric studies to investigate the effects of different design parameters on the connected plate behaviour,including initial sti...
