Abstract

This paper presents the results of 16 tests applied to specimens having a beam section of H - 600×250×12×25 (SN490B). A field-welding connection was adopted, in which beam flanges and web were welded and bolted to the column, respectively. Test parameters were (1) type of connection details (conventional vs. modified), (2) type of run-off tabs (steel tab vs. flux tab), and (3) thickness of through-diaphragm plates (28 mm vs. 32 mm). Specimens with modified details showed larger ductility than those with conventional details, and specimens with steel run-off tabs were also larger in ductility than those with flux run-off tabs. The effect of the thickness of diaphragm plates on ductility was found at most secondary.
