    • Abstract
  • Based on the hinged single-pole model, the paper derives the analytical solution of stability capacity of DSSB (Double-pole Steel-tubular Scaffolding with Bowl-Buckle) considering global effects of vertical tubes, horizontal tubes and bowl-buckle body between two adjacent fasteners. As for the DSSB discussed in the paper, the fasteners have long vertical distance, and the vertical tubes are extended to many stories with no vertical diagonal rods installed. The stability capacity of DSSB obtained by the presented method considering global effects, is much higher than that computed according to hinged single-pole theory, and is more consistent with the finite element results and experimental results. The method could be applied for the design of DSSB.
