EQUIVALENT DAMPING FACTOR OF COMPOSITE RCS FRAMES. IN: COMPOSITE AND HYBRID SYSTEMS

The building standard law of Japan was largely revised in June 1998. With the revision, the adoption of the capacity spectrum method (CSM) for the seismic design procedure is being considered toward the enforcement in June 2000. In the CSM, the estimation of the demand spectrum is one of important issues, because the damping properties of a building should be appropriately considered. The equivalent damping factor of composite RCS buildings consisting of steel beams and reinforced concrete columns is investigated in this paper. The relations between the equivalent damping factor and story drift of RCS joints and frames, which have different joint detail and failure mode, are examined using the existing test results including those obtained in the US-Japan cooperative research program on composite and hybrid structures. It is indicated that the influence of the hysteretic damping factor of composite RCS buildings are particularly when the strength and stiffness of joints are relatively small.
