In this paper, the static characteristics of WF beam to SHS column connections that beam web connected parts were reinforced were investigated by cyclic loading test. The methods of reinforcement were inserting horizontal diaphragm or vertical stiffener inside panel zone. The main parameters were type of reinforcements, width-to-thickness ratio of the column and type of web connection. The test results shows that by reinforcing of web connected parts the maximum strength and the plastic deformation ability of the beam-to-column connection are getting better. The reasons are that the out-of-plane deformation of the column is restrained enough and the bending moment carrying ratio of web connected parts becomes large by reinforcement.
