多数回繰返し載荷を受ける既存超高層鉄筋コンクリート造建築物の地震応答評価

摘要

The study aims to understand the effect of restoring force characteristics on the response behaviors of existing high-rise RC buildings subjected to cyclic loadings. The paper discusses the fact that the degradations of restoring force characteristics subjected to cyclic loadings on response behaviors of structures by applying the models of restoring force characteristics widely used in design and those with the degradations caused by cyclic loadings. Furthermore, it is considered how to introduce the effect into seismic design of high-rise RC buildings with the effect of those restoring force characteristics. Seismic retrofit design is conducted for the bare structures by using the vibration control devices so that effect of the devices on the responses can be investigated under the degrading characteristics of cyclic loadings.%本論では，復元力特性に多数回繰返しによるスリップ性状の変化ゃ耐カ劣化などエネルギー吸収性能の劣化を仮定した解析モデルを用いて，その特性変化が応答結果に与える影響について検討を行つた。本論において検討した項目と本解析範囲で得られた結果について以下にまとめる。
