PROBLEM TO BE SOLVED: To prevent the load resistance of a bridge from decreasing when PC steel members are arranged at the outside by arranging PC steel members at the outside of a concrete member and arranging the PC steel members in the concrete member partly in a specified section to bond with the concrete. SOLUTION: PC steel members 5 are arranged at the outside of concrete 10 and also arranged within the section of the concrete 10 in a specified section to bond with the concrete 10. And hence, defects in the case that the PC steel members 5 are arranged in the concrete 10 can be eliminated. Moreover, since the PC steel members 5 are partly arranged in the concrete 10 in a specified section and bonded with the concrete 10, a part especially requiring a large strength can be sufficiently reinforced by the PC steel members 5 and the decrease of the load resistance which is a defect in the case that the PC steel members 5 are arranged outside can be prevented. And further, a thick part of the concrete 10 formed by the PC steel members 5 is limitted within a short range. |
