Based on the theory of sway frame column, the equation of the effective length factor was derived in this paper. Combined with the characteristics of semi-rigid joints, the linear stiffness correction factor of horizontal bar was introduced, and the equation of effective length correction factor was obtained. By using MATLAB programming method, the three-dimensional relationship between the effective length correction factor and the influencing factors was obtained, and the entire process of the stability bearing capacity of the disc-buckle type high support system was described in detail, which improves the stability calculation theory of the high support system. The influence of setting parameters, joint bending stiffness, geometrical size, and material properties on the effective length correction factor is studied. Simultaneously, the joint bending stiffness of semi-rigid joints is determined. The area of the effective length correction factor is analyzed to optimize the design of the setting scheme using horizontal bars and vertical poles of different sizes. The results show that the lift height significantly affects the effective length correction factor during the load bearing process; the factor decreases with increasing lift height. Large transverse and longitudinal distances influence this rule during the initial load bearing. When the joint bending stiffness is less than 100 (kN·m)/rad, the effective length correction factor decreases rapidly with an increase in joint bending stiffness. When the joint bending stiffness is greater than 100 (kN·m)/rad, the effective length correction factor is unaffected by the joint bending stiffness. When the joint bending stiffness is large at initiation of loading, the effective length correction factor decreases with an increase in the outer diameter of the horizontal bar. When the joint bending stiffness is small, the effective length correction factor increases with an increase in the section size of the vertical pole. Therefore, the outer diameter of the horizontal bar significantly affects the effective length correction factor, and a larger diameter is more conducive to the overall stability. Furthermore, the elastic modulus effects the effective length correction factor for the unstable support system.

考虑节点弯曲刚度和几何尺寸的盘扣式脚手架有效长度修正系数[J].

本文基于防倾框架柱理论，推导了有效长度因子的计算公式。结合半刚性节点的特点，引入了单杠的线性刚度修正系数，得到了有效长度修正系数方程。采用MATLAB编程方法，得到有效长度修正系数与影响因素之间的三维关系，详细描述了圆盘扣式高支撑系统稳定承载力的全过程，提高了高支撑系统稳定性计算理论 研究了设置参数、接头弯曲刚度、几何尺寸和材料特性对有效长度修正系数的影响。同时，确定了半刚性接头的接头弯曲刚度。分析有效长度修正系数的面积，优化使用不同尺寸的水平杆和垂直杆的设置方案设计。结果表明，提升高度显着影响承载过程中的有效长度修正系数；该系数随着提升高度的增加而减小。较大的横向和纵向距离会在初始承载期间影响该规则。当关节弯曲刚度小于 100 (kN·m)/rad 时，有效长度修正系数随着关节弯曲刚度的增加而迅速减小。当接头弯曲刚度大于 100 (kN·m)/rad 时，有效长度修正系数不受接头弯曲刚度的影响。当加载开始时节点弯曲刚度较大时，有效长度修正系数随着水平杆外径的增加而减小。当节点弯曲刚度较小时，有效长度修正系数随着立杆截面尺寸的增大而增大。因此，单杠外径对有效长度修正系数影响显着，直径越大越有利于整体稳定性。此外，弹性模量影响不稳定支撑系统的有效长度校正因子。有效长度修正系数随着垂直杆截面尺寸的增加而增加。因此，单杠外径对有效长度修正系数影响显着，直径越大越有利于整体稳定性。此外，弹性模量影响不稳定支撑系统的有效长度校正因子。有效长度修正系数随着垂直杆截面尺寸的增加而增加。因此，单杠外径对有效长度修正系数影响显着，直径越大越有利于整体稳定性。此外，弹性模量影响不稳定支撑系统的有效长度校正因子。
