安德固插销式脚手架连接节点的抗弯性能研究
Study on Bending Resistance Performance of ADG Plug-in Scaffolding Joint
摘要
Abstract
Recent developments have seen widespread adoption of Andger(ADG)scaffolding systems in construction.However,recurring structural failures at joint connections have raised significant concerns regarding their safety and stability.This study establishes a semi-rigid finite element model of ADG scaffolding joints using ANSYS software,with experimental validation confirming the model's accuracy.Through numerical simulations,we systematically investigate the influence of four key parameters on joint bending capacity:constitutive material properties of lock pins,pin insertion depth,U-clamp thickness,and pin thickness.Key findings indicate that bending capacity exhibits a positive correlation with the yield strength of the pin material.Increased U-clamp thickness enhances both joint bending resistance and initial rotational stiffness.Conversely,pin thickness and insertion depth demonstrate negligible effects on bending performance.These findings provide critical insights for optimizing the structural design of ADG scaffolding systems.关键词
