[1M14] Effect of analyfical settings on Elastic-Plastic Restoring Force Characteristics of piping support structures

*Tougo Kozuka1, Nakamura Izumi1 (1. TCU)

Keywords:piping support structures, Elastic-Plastic Restoring, Force Characteristics

弾性解析に基づく現行の配管系の耐震設計に対し、弾塑性解析に基づく耐震設計手法の開発が進められている。本研究では配管支持構造物の弾塑性評価取り入れに向け、配管支持構造物の弾塑性FEM解析を行い、復元力特性をひずみ履歴の評価を行った。また、材料特性の設定ばらつき、要素分割が復元力特性、ひずみ履歴に与える影響を調査した。
