| Abstract: | Construction process and technology of prestressed CFRP board reinforced concrete beam are introduced herein, including prestressed CFRP board stretching equipment, reinforcement construction flow and key technical points. Prestressed CFRP board supporting anchorage that is developed independently is adopted to guarantee successful bending test of six pieces of prestressed CFRP board reinforced concrete beam. According to the test results, compared with the non-prestressed CFRP board reinforcement method, prestressed CFRP board reinforcement method can improve bending.capacity and anti-cracking property of components and can be applied in practical projects directly. |
| Keywords: | prestressing CFRP board concrete beam |
