Abstract

The Northridge fractured connections have been so far studied in relation to the weld's material properties. Upon recognition of the fact that the weld forms only part of the entire connection and that column material properties also need to be addressed, Part I, (Righiniotis TD, Lancaster ER, Hobbs RE. Fracture strength of a moment resisting welded connection under combined loading. Part 1—Formulation. Journal of Constructional Steel Research 2000:56(1):17–30), presented the formulation which determines the stress intensity factors for a column with a cracked flange when the former is subjected to tension, bending, stress concentrations and welding residual stresses. In this paper the results of this formulation are put forward and the fracture strength of specific Northridge connections is considered.
