“…Additionally, the results highlighted the limited strength of the shear-tab connections in resisting the progressive collapse once a gravity column is lost. Hayes et al (2005) [8] investigated the possible relationship between seismic detailing and blast and progressive collapse resistance. The authors analyzed three possible strengthening schemes for the Alfred P. Murrah Federal building if it were located in a seismically active region.…”

“…Pushdown analysis was also used in studies conducted by Lu et al [13], concluding that failure modes were correctly determined using nonlinear static analysis and that robustness can be quantified using the residual reserve strength ratio. Results from simulations carried out by Khandelwal et al [14] and Hayes et al [15] showed that frames designed using seismic design provisions presented greater robustness.…”

Nowadays, many buildings with steel Moment Resisting Frames (MRF) are built in seismic zones when seismic codes are at its early stages of development, and as such, these structures are often designed solely to resist lateral wind loads without providing an overall ductile mechanism. On the other hand, current seismic design criteria based on hierarchy of resistance allow enhancing the structural ductility and controlling the structural plastic behaviour. Therefore, seismic design criteria might also be beneficial to improve the structural robustness. In order to investigate this issue for steel MRF, a parametric study based on pushdown analysis and on the Energy Balance Method is described and discussed in the present paper. With this regard, the following cases are examined: (i) MRF not designed for seismic actions and (ii) MRF designed for seismic actions. The investigated parameters are (i) the number of storeys, (ii) the interstorey height, (iii) the span length, (iv) the building plan layout and (v) the column loss scenario. Results show that the low-rise and long span structures are the most prone to progressive collapse and that the elements in the directly affected zone of the wind designed 8 storey structures respond in the elastic range. Structures designed according to the capacity design principles were found to be less robust than wind designed structures that are characterized by strong beams and weak columns. The number of elements above the removed column and size of beam cross section were found to be key parameters in arresting progressive collapse.

“…Thus, recently, some attention has been given to examining the validity of this view. Readers interested in these early assertions should study material on joints and continuity (Hayes J.R. et al, 2005, Gurley, 2008 as well as the FEMA report on the Murragh building collapse (FEMA 277, 1996). Some basic findings from the Imperial work are presented herein.…”

It has sometimes been presumed that the ability of buildings designed to resist seismic loading will inherently be superior to that of those designed for nonseismic conditions. This assertion is tested herein by comparing the resistance to progressive collapse of a series of representative moment frames. The assessments are undertaken using the alternate load path approach to sudden column loss, implemented by means of a technique developed at Imperial College London. The findings confirm that the greater moment capacity and rotational stiffness possessed by the arrangements used to provide the moment connections between the beams and the columns generally result in better performance. However, some features specifically adopted to improve seismic performance are found to be very poor in terms of their resistance to progressive collapse.
