VERIFICATION OF IDENTIFICATION METHOD FOR NONLINEAR HYSTERETIC SYSTEMS UTILIZING SHAKING TABLE TESTS OF FULL-SCALE 4-STORY STEEL BUILDING

Abstract

The already proposed identification method for nonlinear hysteretic systems is applied to shaking table tests of a full-scale 4-story steel building at the E-Defense. The structure is modeled as a 4DOF nonlinear shear building in each horizontal direction. The nonlinearity in stiffness is expressed as the Bouc-Wen hysteretic model. The identified hysteretic curve is compared to the corresponding experimental result.
