Improvement of shear and ductility of reinforced concrete columns by wrapping of continuous fiber-reinforced polymer sheet
The Concrete Committee of the Japan Society of Civil Engineers (JSCE) has set up a technical committee on the retrofit of concrete structures by continuous fiber-reinforced polymer sheet (CFRP sheet). The
technical committee has been working to make a recommendation for 1 1/2 years and has proposed the first draft. This paper describes some parts of the recommendation, in particular, on how to design the
shear strengthening and the ductility improvement by use of CFRP sheet. In addition, discussion is extended to the proposed test methods on the tensile strength and the bond strength of CFRP sheet.
