摘要
为确定构配件不同构造因素下悬挑脚手架的稳定承载力,利用ANSYS有限元软件对扣件式钢管脚手架稳定承载力的影响因素以及不同构造因素下悬挑脚手架的屈曲变形进行了数值模拟分析.分析结果表明:脚手架稳定承载力受剪刀撑斜杆与大横杆夹角的变化影响显著,立杆间斜撑的设置方式对脚手架承载力有明显影响;增加斜撑长度,不同步距下脚手架承载力随之逐步下降,单位连墙件承载面积越小,脚手架的整体稳定性越好,稳定承载力越大.
To determine the stable bearing capacity of cantilevered scaffold under different structural factors,ANSYS finite element software was used to analyze the affecting factors of stability capacity for steel tubular scaffold and buckling of cantilevered scaffold under different structural factors.The results confirm：The change of angle between scissors and the ground has a significant impact on the scaffolding stable capacity,so do the settings of diagonal braces between vertical rods.Along with the length of diagonal braces increases,the stability of scaffold gradually declines under different step distance.The smaller the units wall pieces bearing area is,the higher the overall stability of the scaffold,and the greater the stability of the bearing capacity.
