Fracture strength of a moment resisting welded connection under combined loading - Part II - results

The Northridge fractured connections have been so far studied in relation t o the weld's material properties. Upon recognition of the fact that the wel d forms only part of the entire connection and that column material propert ies also need to be addressed, Part I, (Righiniotis TD, Lancaster ER, Hobbs RE. Fracture strength of a moment resisting welded connection under combin ed lending. Part 1-Formulation. Journal of Constructional Steel Research 20 00:56(1):17-30), presented the formulation which determines the stress inte nsity factors for a column with a cracked flange when the former is subject ed to tension, bending, stress concentrations and welding residual stresses . In this paper the results of this formulation are put forward and the fra cture strength of specific Northridge connections is considered. (C) 2000 E lsevier Science Ltd. All rights reserved.
