METHOD FOR EVALUATING STRENGTH OF STEEL PIPE CONCRETE COLUMN/BEAM JOINT

摘要

PROBLEM TO BE SOLVED: To determine a safety ratio associated with strength, by determining the evaluated strength, even if a yield does not occur in a joint.;SOLUTION: Among joints between a steel pipe concrete column 4 and a steel-frame beam 3, a joint between a tension-side flange 3F of the steel-frame beam 3 and the steel pipe concrete column 4 is split into an end area e and a central area m. The resultant force of the end yield strength of the end area e and the central yield strength of the central area m is set as the evaluated strength. In this case, when only the flange 3F yields, the joint does not yield and the evaluated strength does not exist, the thickness dimension of the steel pipe decreases in numeric value, so that at least two points, where the yield strength can be determined, can be assumed; and the evaluated strength for the corresponding thickness dimension of the steel pipe is computed from the tendency of a change in the thickness dimension of the steel pipe and the evaluated strength at the two points.;COPYRIGHT: (C)2008,JPO&INPIT
