Seismic Performance Evaluation of flat Plate Structures Retrofitted with Steel Plates and Braces
강판과 가새로 보강된 무량판 구조물의 내진 성능 평가
Abstract
In this study 3- and 6-story flat plate structures designed only for gravity load are retrofitted with steel plates and braces and their seismic performances are evaluated to verify the effect of seismic retrofit. According to the analysis results obtained from nonlinear static analysis both the strength and stiffness are significantly enhanced as a result of the seismic retrofit. When buckling-restrained braces are used instead of conventional braces, the structures show more ductile behavior, especially in the 3-story structure.
