Effect of Semi-Rigid Connection and Pole in Different Flat on the Overall Steady-State Load-Bearing Capacity of the Steel Tubular Scaffold with Couplers

Abstract

Nonlinear analysis of the steady-state load-bearing capacity of steel tubular and the steady-state load-bearing capacity of scaffold was simulated by ANSYS considering semi-rigid connection and pole in different flat. Quantitative standard of the steady-state load-bearing capacity to the steel tubular and the steel tubular scaffold with couplers is used in ANSYS. The effect of semi-rigid connection on the overall steady-state load-bearing capacity of the steel tubular scaffold with couplers is great. The effect of pole in different flat on the overall steady-state load-bearing capacity of the steel tubular scaffold with couplers is smaller. It’s generally recognized that nodes of vertical bars and horizontal bars of steel tubular scaffold by fasteners is not rigid, but semi-rigid; is not in the same plane, but in a different surface. This structural model directly affects the steady-state load-bearing capacity of scaffold. In this paper, ANSYS software was used for nonlinear analysis of steel tubular scaffold, the same models with experimental value [4] was used to establish standards for determining the instability load [1] [2], to determine the effect of bar coplanar and semi-rigid connections on steel tubular scaffolding overall stability capacity.
