A new type of moment frame is introduced in this paper The section of beams and columns are both the wide flange type. These are connected byknee braces with damping mechanism using high strength bolts. Knee brace dampers are specified to absorb the seismic energy effectively and to maintain beams and columns in elastic range. Seismic design method of the frame are presented and the dynamic responses of the frames against earthquakes are compared to the conventional rigid frame with rectangular hollow section columns.
