In order to study the structural stability of the disc-buckle type formwork support, the multi-parameter experimental analysis of the disc-buckle type formwork support structure was carried out by using experimental and finite element analysis method. The influence parameters of working conditions, lift height, diagonal bracing and sleeve on the structural stability bearing capacity was mainly considered. The regularity of the buckling direction of the vertical pole, the stress at each typical position on the vertical pole and the axial force of the vertical pole was studied based on the experimental results. Based on the characteristics of semi-rigid connection joints, the correctness of the experimental results was verified by finite element analysis, and the results show that reducing lift height and arranging diagonal bracing have remarkable influence on improving the structural stability bearing capacity. The usage of sleeves has little influence on the structural stability, and the corner pole was the worst position of the overall structural stability. The factors of working conditions and diagonal bracing have the remarkable influence on the buckling direction of the vertical pole. The factor of working condition has the most obvious influence on the stress uniformity of the vertical pole. The axial force of the vertical pole in the disc-buckle type formwork support structure presented a relatively uniform state from bottom to top in the loading process. The arrangement of diagonal bracing and the usage of sleeves have an influence on the uniformity of the axial force of the vertical pole. Compared with the finite element results, the error of the structural stability bearing capacity was within 6%, indicated that the finite element can accurately simulate the structural stability bearing capacity.

为研究圆盘扣式模板支架的结构稳定性，采用实验和有限元分析方法对圆盘扣式模板支架结构进行多参数试验分析。主要考虑工况、提升高度、斜撑和套筒等参数对结构稳定承载力的影响。根据试验结果，研究了立柱屈曲方向、立柱各典型位置应力及立柱轴向力的规律性。根据半刚性连接节点的特点，通过有限元分析验证了实验结果的正确性，结果表明，降低提升高度和布置斜撑对提高结构稳定承载力有显着影响。套管的使用对结构稳定性影响不大，角杆是整体结构稳定性最差的位置。工况和斜撑等因素对立杆的屈曲方向有显着影响。工况因素对立杆受力均匀性的影响最为明显。圆盘扣式模板支撑结构中立柱的轴向力在加载过程中自下而上呈现相对均匀的状态。斜撑的布置和套管的使用对立杆轴向力的均匀性有影响。
