<P>PROBLEM TO BE SOLVED: To provide a junction structure of a beam member such as a short-span beam made of fiber-reinforced cement-based material and a vertical member such as an earthquake-resisting wall or a column, the junction structure having superior toughness against large deformation of the beam member. <P>SOLUTION: There is provided a junction structure comprising: a beam body 11 which is a precast member having beam main reinforcements 13 and stirrups embedded in advance and made of a fiber-reinforced cement-based material prepared by mixing short fiber with cement, the beam main reinforcement 13 projecting from a side end face; and a core wall 20 which has column reinforcements 21 and lateral reinforcements 25 orthogonally arranged and is made of concrete. The beam main reinforcements 13 and column main reinforcements 21 are orthogonally arranged, an end stirrup 18 surrounding a periphery of a plurality of beam main reinforcements 13 is arranged between a column main reinforcement 21a of the core wall 20 on the side closest to the beam body 11 and a side end face of the beam body 11, and the concrete is cast. <P>COPYRIGHT: (C)2013,JPO&INPIT |
