PREDICTION OF MAXIMUM EARTHQUAKE RESPONSE STORY SHEAR OF WALL-FRAME BUILDINGS WITH HYSTERESIS DAMPERS CONSIDERING HIGHER MODE DAMPING

Abstract

The authors proposed a new type of structural-wall system(EDSWs) consist of wall panels, coupling steel girders and edge columns which possesses the large energy dissipating capacity and the function which uniforms drift angle of each story.
Because the shear force that is attributable to higher mode responses concentrates on wall part, it is vital to predict higher mode response for the desirable design of EDSWs or wall-frame system including EDSWs.
The authors proposed the prediction of maximum earthquake response story shear not performing dynamic analysis but only performing static analysis by converting a multi-story building into equivalent single degree of freedom system, which can be applied to the Capacity Spectrum Method.
