STRENGTH ESTIMATING METHOD FOR STEEL PIPE COLUMN AND BEAM JOINT

摘要

PROBLEM TO BE SOLVED: To make it possible to determine the yield strength of a joint between a steel pipe column and a beam more accurately and easily with less labor.;SOLUTION: The yield strength cPy of the joint between the steel pipe column and the beam can be calculated from an outer diameter Dp of a thickened steel pipe portion K2, a pipe thickness Tp of a thickened steel pipe portion K2, a joint width Bf' including an excess metal of weld of the thickened steel pipe portion K2 and a beam flange BF of the steel pipe column and beam joint, a joint height Tf' including an excess metal of weld of the thickened steel pipe portion K2 and a beam flange BF, an axial tension ratio (np) which is a ratio between the axial tension at the thickened steel pipe portion and the yield strength in axial direction of the thickened steel pipe portion, an yield unit stress fσy of a beam member, and an yield unit stress cσy of the column member based on the following estimation equation (1): cPy=C 1.DpC2.TpC3.Bf'C4.Tf'C5.(1-np)C6.fσyC7.cσyC8...
