단면증설된 R/C보의 보수.보강 효과 연구
A Study on the Repair and Strengthening Effencs of R/C Beams with Enlarged Section
초록
Reinforced Concrete structures need repair and rehabilitation due to the deterioration such as crack, spalling and disintegration. Numerous repair materials which are currently used in cinstruction fields witdout any specifications are examined in terms of their serviceabilities and effectiveness. In this paper sections of R/C beams are enlarged with repari material(epoxy, latex, premix), and then they are strengthened with rebar, steel plate of CFRP sheet on the tension side. Structural behaivior of strengthened beams are investigated under stactic tests and compared with each parameters.
