Concrete stave silos are segmental structures which are cylindrically assembled from precast concrete blocks and held together by exterior posttensioned steel hoops. To simulate the seismic behavior of such stave silos the modified Jennings' hysteresis model is adopted on basis of model testing. In this hysteretic modeling, a stiffness reduction factor due to structural discontinuity is introduced. Earthquake response analyses of a l/8-scale model stave silo are carried out and compared with its experimental results. A significant influence of hysteretic dissipation energy is also investigated. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
