N2 - There are some differences in steel structures from the point of view of seismic designs between the USA and Japan. Japanese typical frames are spatial moment resisting frames. USA frames are the perimeter frames, and the columns inside the frames are designed as gravity columns, which support only the weight of the buildings. Such columns may divide the shear force over the height of the frame and work as damage control systems. This study clarifies the drift deformation concentration for the standard steel moment resistant frames in the USA and Japan. The equations for the drift concentration are developed under the equilibrium conditions, and compared with the push over analyses results.
