PURPOSE: A joint structure of a precast concrete column and girder for reducing the member force of a long span precast concrete girder is provided to ensure the integrity of a joint part and to reduce the size of members and the amount of bar arrangement at the same time by decreasing shear force and moment in the end of a precast concrete beam member. CONSTITUTION: A joint structure of a precast concrete column and girder for reducing the member force of a long span precast concrete girder comprises a first sheath pipe (140) and a second sheath pipe, and a tendon. A precast concrete column (100) is pierced into an arch shape and is equipped with the first sheath pipe. The second sheath pipe is connected to the first sheath pipe and penetrates the lower part of a precast concrete beam (200) from the lateral end of the precast concrete beam. The tendon penetrates the first and second sheath pipes and is serialized using a post tension method by tensioning the tendon in both sides precast concrete beam held in the precast concrete column. |
