PROBLEM TO BE SOLVED: To provide a column and beam joint part having excellent earthquake-proof performance without relying on a yield ratio YP of a steel material used as a column member. SOLUTION: In this column and beam joint part, bending proof stress of a joint part panel provided at a nodal point of a column and a beam is less than sum of bending proof stress of the column being upper and lower parts of the joint part panel. Or when degree of yield stress of the joint part panel, plate thickness of the column and the beam, and degree of yield stress are prescribed as parameters and proof stress and plate thickness of the steel material constituting it are equal to proof stress and plate thickness of the steel material used in the column being upper and lower parts of the joint part panel, respectively, proof stress and plate thickness of the steel material used in the joint part panel are prescribed using additional shaft force, distance between beam flange centers, distance between column flange centers, and yield ratio of the steel material used in the joint part panel as parameters. This column and beam joint part has at least one column and beam joint part in a steel rigid frame framework having a displacement angle between yield layers of 1/100 or more and uses a base of column having lower proof stress than the column in a base of column of a column in the lowest layer.
