PROBLEM TO BE SOLVED: To provide a connection load bearing capacity evaluation method for a column-beam connection structure that enables a column flange plate thickness and a web plate thickness to be reduced further, taking into consideration appropriately a load burdening effect of concrete.SOLUTION: A connection load bearing capacity evaluation method is for a non-diaphragm-type column-beam connection structure with a steel framed reinforced concrete column 11, a steel beam 21, and a connection 31 where the beam is connected to the column. The column 11 includes a steel column 12 having a web 14 and a flange 13. The beam 21 includes a web 24 and a flange 23, and is connected to the flange 13 of the steel column 12 at the connection 31. An evaluation is made on the connection 31, taking into consideration bearing capacity of concrete on an inner side D1 in a thickness direction of the flange of the steel column to withstand bearing fracture, in which the flange of the steel column is deformed toward the inner side in the thickness direction of the flange, when force generated by the flange on a compression side of the beam on the flange of the steel column is exerted to press-in the flange of the steel column in a thickness direction D, in addition to bearing capacity of the steel column.SELECTED DRAWING: Figure 3
