振動台を用いた鋼構造骨組の動的加振実験

Abstract

Dynamic failure tests of one-storied steel pure frames and braced frames by means of ashaking table and dynamic response analyses are performed. Model structures are composedof four columns, a rigid roof and a rigid base and, in the case of a braced frame, two pairsof K-type braces are added. They are subjected to the base motion simulated to the N-Scomponent of 1940 El Centro acceleration record, and a dynamic response and a process tofailure are accurately obtained. From the comparison between the test and the analysis, it is recognized that the time history of response acceleration can be predicted in a sufficientaccuracy, but that of a story drift cannot always fall on the experimental result due tothe inaccurate estimation for the magnitude of inelastic flow.
