3階建て鉄骨ラーメン構造住宅における常時微動測定調査および固有振動数の推定

抄録

In this study, the authors conducted a microtremor measurement on 15 three-story steel-frame houses and investigated their natural frequencies and damping ratios. Additionally, the authors propose a new method for estimating the natural frequencies of steel-frame houses at the newly constructed state. The proposed method is an evaluation method that does not require modeling based on structural design process, and the validity of the estimated natural frequency which was obtained using this method was verified.
