PROBLEM TO BE SOLVED: To secure integrity as a structure while reducing prestress when a concrete structure is constructed by connecting multiple concrete solidified wastes using a tensioner and imparting prestress thereto.SOLUTION: In a structure constructed by connecting multiple concrete solidified wastes using a tensioner and imparting prestress thereto, the magnitude of prestress is reduced as follows: a combined stress of a bending unit stress by a design load acting on the connected concrete solidified wastes with a compressive stress by the prestress given by the tensioner in a joining surface with the multiple concrete solidified wastes connected thereto or a cross section in the vicinity thereof becomes the compressive stress in a place where the tensioner is present or a position of resultant force of the prestress by multiple tensioners; and alternatively, becomes the tensile stress in the place where the tensioner is present or in the vicinity of the surface of the concrete solidified waste spaced apart from the position of the resultant force of the prestress by the multiple tensioners.SELECTED DRAWING: Figure 4 |
