The characteristics of integral forced prformance for seel tubular high scaffold with couplers were introduced and deficiencies were pointed out in the paper. Integral forced prformance for steel tubular high scaffold with couplers was simulated by finite element software ABAQUS. Couplers joint was simulated with nolinear elastic spring element model. Eigenvalue buckling analysis was used to get the most stability capacity. The simulated result agrees well with previous experimental result.
