Abstract:
In order to research the rules of bearing capacity of axial-compression reinforced concrete column strengthened with CFRP, the reliability computing method of axial-compression reinforced concrete column based on JC method was put forward, the corrosion rate, amount of CFRP and the load effect ratio were taken into account, the reliabilities were calculated of numerical examples by scientific computing software MATLAB. The analysis results show that: when the reinforced concrete beam is corroded, the reliability index is too small, after the beam is reinforced by 4 layers of CFRP, the reliability index increases 33%; the reliability index of the structure increases with the increase of the load effect ratio, the corrosion rate has a big influence on the reliability index of the reinforced concrete beam, the reliability index of the structure decreases with the increase of the corrosion rate, the reliability index improves 3.7%~8% when increase one layer CFRP.
