TL;DR: In this paper, the performance of four types of beam-to-column connections, namely, the welded cover plate flange connection (CWP), the haunch end plate bolted connection (EPH), the reduced beam section welded connection (RBS), and the unstiffened extended end-plate bolted connection(EP), against progressive collapse was investigated.

TL;DR: In this article, the response of two-way steel frame systems under the removal of a central column was investigated, and an experimental test was carried out, and then, a numerical model was validated using the advanced nonlinear dynamic analysis software Extreme Loading for Structures.

TL;DR: In this article, the authors investigated the resistance of seismically designed steel-frame buildings to progressive collapse, focusing on the contributions of the floor system and beam-to-column connections, with the purpose of determining some robustness criteria, using as reference the ratio of the failure load to nominal gravity load.

TL;DR: In this article, the results of a combined experimental/numerical program, which focused on the response of steel frames to close-in detonations, were presented, which indicated that the local failure mechanism and resistance to progressive collapse of steel building frames depend very much on the blast load parameters and the level of gravity loads in columns.

TL;DR: This paper presents the results of a study devoted to the evaluation of steel frame response following the loss of a column, where several full-scale structures are investigated for a sudden column loss scenario.
