Research Abstract	In this study, the effects of joint panel shear deformation to elastic plastic behavior of Moment Resisting Steel Frames are investigated conducting a series of loading tests and FE analyses with varying joint panel strength ratio, weld detail and width to thickness ratio of beam flange. The ultimate strength of MRFs that is designed under the weak panel design concept is decreased by decrease of the panel strength ratio because of the strain concentration at beam flange near the weld. Regardless of this strength reduction, the cumulative plastic deformation capacity of MRFs with weak panel design concept, increases by decrease of the panel strength ratio.
