복합패널(GSP)을 사용한 철근콘크리트보강보의 휨성능에 관한 수치해석적

다국어 초록 (Multilingual Abstract)

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.
