METHOD FOR EVALUATING STRENGTH OF STEEL PIPE CONCRETE PILLAR/BEAM JUNCTION PART

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method for reducing the degree for excessively evaluating the strength of a junction part. SOLUTION: The junction part between a flange 3F at the pull side of a steel frame beam 3 and a steel pipe concrete pillar 4 out of a steel pipe concrete pillar/beam junction part is divided into end regions (e) near both ends in the width direction of the flange and a central region (m) between them, the yield strength of a steel pipe 1 and that of the flange 3F are obtained for each of the end region (e) and the central region (m), a smaller one out of the yield strength of the steel pipe 1 and that of the flange 3F is set to end yield strength, yield obtained by multiplying a smaller one out of the yield strength of the steel pipe 1 and that of the flange 3F by a stress block coefficient is set to central yield strength for the central region (m), and the total of the end yield strength and the central yield strength is set to evaluation strength.
