| Abstract: | According to the Synthetical theory on cracks of reinforced concrete members,this paper presents a calculation method on the crack width of RC beams externally strengthened with CFRP(Carbon Fiber Reinforced Polymer/Plastic) sheets.Comparison between the calculation result and the experimental data shows that the proposed method can be used to calculate the bending crack width in the service stage. |
