PROBLEM TO BE SOLVED: To provide a connecting structure for reinforced concrete column and steel-framed beam improving the shearing yield strength of a panel zone. ;SOLUTION: In this connecting structure, large-diameter reinforcing bars 6 are buried in the main reinforcements of a precast reinforced concrete column 1 via two cross joints 3 and different-diameter mechanical joints 4 at the interval to pinch the flanges of a steel-framed beam 2 to be connected near the panel zone of a precast reinforced concrete column 1 on the lower floor so that they are protruded from the upper end of the precast reinforced concrete column 1. The flanges of the steel-framed beam 2 are pinched by the cross joints 3 and fastened by high-strength bolts, and the main reinforcements 5a of the precast reinforced concrete column 1a of the upper floor are connected to the large-diameter reinforcing bars 6 protruded from the upper end of the precast reinforced concrete column 1 via different-diameter sleeve joints 7.;COPYRIGHT: (C)1998,JPO
