This paper presents experimental efforts in steel framed substructure with bolted flange plate (BFP) connections subjected to progressive collapse. A simplified modelling approach based on the shell element and ductile fracture criterion is introduced. The method shows a close correlation to the existing experimental data and demonstrates better computing efficiency than solid element based simulation strategy. A number of parametric studies were conducted based on the validated numerical method to evaluate the influence of varying connection configurations on the progressive collapse resistance of the steel substructures. It is indicated that the connection with welded flange plates can lead to greater flexural strength than that with bolted angles and the application of welded haunch plates can arrest fracture failure on the welds within the beam-column joint. Predictions are made for fracture potential of different connections in resisting progressive collapse.
