A Consideration on the Equivalent Linearization of Restoring Force Cearacterisitics of Structures

“…Instead of steel specimens frames, etc. are used in plastic region repetitive loading tests by many researchers such as lgarashi et al 5,Hanson&}etc. Lots of studies the restoring force characteristics of reinforced concrete frames(abbreviated as RC in the following) have been here and Odaka and Saito" show that every shape of hysteretic curves of RC frames from hi-linear type to medium type between hi-linear and double hi-linear5 as applied axial force is changed and Johnston9 propose Degrading Stiffness system of a multi-linear type for RC frames. Aoyama et al10) investigate the of RC portal frames subjected to reversal of horizontal under vertical loading and clarify the mode of failure, frame stiffness and its reduction.…”
