WES 2808 for Brittle Fracture Assessment of Steel Components under Seismic Conditions – Part V: Equivalent CTOD ratio for correction of constraint loss in beam-to-column connections
Year: 2016
Type: article
Abstract: Crack-tip plastic constraint in beam-to-column connections with a surface crack 1) at the bottom of a conventional type of weld access hole and 2) at weld start/end points of butt welds to connect beam flange and diaphragm subjected to bending moment were analyzed by FEM. The equivalent CTOD ratio β used for engineering toughness correction for constraint loss for the beam-to-column connections are compared with those for the wide plate components with the same size of a crack subjected to tension load. Then, the analyses of β by means of the wide plate component, CSCP and ESCP, are conducted, and the crack depth effect on β is formulated with focusing on crack depth ratio a/t .
