강판 및 CFS를 사용한 단면증설된 보의 휨보강에 관한 해석적 연구
Analysis Study on the Flexural Behaviour of Beams with Enlarged Section using Steel Plate of Carbon Fiber Sheets(CFS)
초록
An analytical method based on the nonlinear layered finite element method is developed to simulate the load-dsflection behavior of strengthened beams. Beams considered in this study are the ones strengthened either with external steel plate or Carbon Fiber Sheets(CFS) bonded to the overlay soffit. The theoretically obtained load-deflections and strains of the strengthened beams are compared to the corresponding experimental values. Parametric studies are, then. performed using the developed model to investigate the effects of design variables on the flexural behavior of the strengthened beams. Simply supported beams under monotonically increasing loads sre considered exclusively.
