PROBLEM TO BE SOLVED: To design a pretension system precast prestress concrete girder.SOLUTION: In a design method of RC-PC prestress concrete girder, a first anchorage length being the anchorage length of a tension material 2 when introducing tension force and a second anchorage length being the anchorage length of the tension material 2 in long-term load time or the anchorage length of the tension material 2 after an earthquake load acts, are set, and sticking splitting of the tension material 2 when introducing the tension force in the first anchorage length, is tested, and the second anchorage length is formed in a reinforced concrete structure of the tension force regarded as zero, and a beam central part 11 except for it is formed in a prestress concrete structure, and stress and deflection of the precast prestress concrete girder are tested.SELECTED DRAWING: Figure 1 |
