Outline of Final Research Achievements |
The authors are conducting research to clarify the seismic performance of the frame with R-brace. In previous studies , research was conducted experiments of R-brace and numerical analysis of one-storyone-bay frame. In this paper numerical analysis with multi-story-multi-bay is carried out and performance of R-brace is discuss. As a result. The performance of R-brace is restrained residual deformation when the burden is large. Furthermore, it is possible to decreased the increase of residual deformation when even if multi-earthquakes occur, and to restrain occurrence of residual deformation.

Academic Significance and Societal Importance of the Research Achievements |
通常,構造物に残留変形が発生する場合,複数回の地震動を与えると,一方向への変形の蓄積が観察され,連続的に構造物の耐震安全性を検討しなければならない.これに対し,原点立上がり型復元力特性を有するブレースを設置し,構造物全体に同復元力特性を分布させることで,複数回発生する地震動に対して構造物の耐震安全性を地震の回数,すなわち繰返し回数という観点で議論できることを明らかにした. 地震応答に対する振動制御として,応答理解の単純化を図れる可能性を提示できた.
