Abstract:

Article Preview

Base on two groups of comparison tests of bearing capacity of three rectangle section of steel concrete beams with different strength grades, the research analyzed the effect of concrete beams strengthened by carbon fiber sheet and strengthened jointly by carbon fiber sheet and external prestressing on the bearing capacity, failure modes, strain states, rigidity and ductility.The results show that bending resistance of steel concrete beams strengthened jointly by carbon fiber sheet and external prestressing can be improved obviously, and the usage performance and strengthened effect are obvious too.
