Stability theory of semi-rigid steel frame was used to calculate the bearing capacity of S1 model,the comparison of the result with the numerical result verified stability theory of semi-rigid steel frame is feasible in calculating bearing capacity of systems. Rotation performance of right angle couplers were tested,and moment-rotation curve of couplers were obtained.
