Ultimate Tensile Strength of Flanges and Webs of H - Shaped Beam Joints with High - Strength Bolts

Abstract

Based on the results of the tests on the bending of H-shaped steel beams with high-strength bolt joints, we proposed formulas to predict the ultimate tensile strength of flanges for outer tearing fractures, and webs for inner tearing fractures and end fractures. The applicability of the prediction formulas, which were previously obtained from the steel plate joint tests, to the flanges and webs was discussed. SS400 steel, 590Mpa-grade and 780Mpa-grade high-quality steels were used for test specimens.
