| Research Abstract |
There are some differences in the steel structures from the view of seismic designs between U.S.and Japan. Japanese typical frames are spatial moment resisting frames. U.S. frames are the perimeter frames, and the columns inside the frames are designed as the 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 the damage control systems. This study clarifies the drift deformation concentration for the standard steel moment resistant frames in U.S.and Japan. The equations for the drift concentration are developed under the equilibrium conditions, and compared with the push over analyses results.
