복합패널(GSP)을 사용한 철근콘크리트보강보의 휨성능에 관한 수치해석적 연구

About flexural strengthening effect of reinforced concrete beam, a reinforcing method of construction that consists of fiber-steel plate composite panels(GSP) is under development at present. There is also a high demand for precise behavior of structures for its economical and efficient planning. That is, a reliable research must be undertaken that could allow precognition of intensity and behavior in conjunction with the securement ductility and character. As a result of making efforts to resolve the issues, many experimental researches and structure interpreting techniques exist today. The research verified the validity of interpretation by comparing and analyzing existing experimental values using a grudge element interpretation program. Various interpretation models have been proposed by introducing a reinforcing method for shearing flexural of strengthened reinforced concrete beam with a composite panel(GSP) as an additional variable. Lastly ductility and beam capacity were examined and compared with an interpretation model at varying levels of reinforcement, reinforcement method, load-displacement relationship and crevice phase.
