プレストレストコンクリート構造のエネルギー吸収性能を向上する摩擦ダンパーの開発: 基礎的な数値解析モデルの構築

摘要

PC構造のエネルギー吸収性能を向上する摩擦ダンパーの開発を目的に，銅管補強PC梁に摩擦ダンパーを装着した既往の実験結果に基づいて．摩擦ダンパーのモデル化方法について検討した。本研究より得られた知見を以下にまとめる。%This paper summarizes a friction damper developed in the authors' previous experimental study, and mainly discusses its numerical modeling based on the major findings from the tests. Seismic behavior of a prestressted concrete beam with the friction damper was theoretically represented using simple numerical models. As a result, it was verified that the experimental results, in particular the beam behavior with low to medium damper forces, could be simulated well by the proposed method.
