Significant research effort has been devoted in recent years to the evaluation of the capacity of steel frame structures to resist progressive collapse after sudden column loss. Due to the complex load-structure interaction and material behaviour, it can be very difficult to evaluate the ultimate capacity of structural components using current analytical methods. Therefore considerable research effort has been directed to experimental testing and sophisticated numerical simulations. Although sudden column loss is a dynamic process, most experimental studies on fullscale or scaled down specimens were performed under quasi-static loads. This paper presents the results of a study devoted to the evaluation of steel frame response following the loss of a column. Advanced numerical models are calibrated using experimental test results and dynamic increase factors are studied. Several full-scale structures are investigated for a sudden column loss scenario.

In seismic design, structural irregularity has been found to have a significant influence on structural response. The impact of structural irregularity on the global response of steel frame structures subjected to blast loading has not been examined. In the paper, six...

The paper investigates the role of beam-to-column connections in mitigation the progressive collapse of multi-story steel frame buildings in case of column loss. On this purpose, a set of moment frames with different beam-to-column connections is designed following...

Capacity of multi-storey steel frame buildings to resist extreme loading may depend on the performance of beam-to-column connections. If catenary action forms, this results in large axial force demands in beams and therefore it is necessary to take into account the...
