One flush end-plate external joint under monotonical loading and the other four joints under cyclic loading were tested. Failure modes and the effects of reinforcement ratio and concrete in column flange were synthetically considered during cyclic loading. Results of the experiments show that external flush end-plate composite joint also have quite hysteretic behaviors, better strength resistance and stiffness that are worth to promotion in seismic area.Based on experimental results and plastic analysis simplified formulas on moment resistance of semi-rigid composite joints were introduced.
