“…The report has also been slightly modified and presented as a journal publication (Kodur et al 2011). The key objective of the workshop upon which the report is based was apparently "to enhance the research and training activities in the fire safety area by identifying the needs for research and for state-of -the-art improvement" ).…”

In recent years, large-scale structural fire testing has experienced something of a renaissance. After about a century with the standard fire resistance test being the predominant means to characterize the response of structural elements in fires, both research and regulatory communities are confronting the many inherent problems associated with using simplified single element tests, on isolated structural members subjected to unrealistic temperature-time curves, to demonstrate adequate structural performance in fires. As a consequence, a shift in testing philosophy to large-scale non-standard fire testing, using real rather than standard fires, is growing in momentum. A number of custom made, non-standard testing facilities have recently been constructed or are nearing completion. Non-standard fire tests performed around the world during the past three decades have identified numerous shortcomings in our understanding of real building behavior during real fires; in most cases these shortcomings could not have been observed through standard furnace tests. Supported by a grant from the Fire Protection Research Foundation, this paper presents a review of relevant non-standard structural fire engineering research done at the large-scale around the world during the past few decades. It identifies gaps and research needs based both on the conclusions of previous researchers and also on the authors' own assessment of the information presented. A review of similar research needs assessments carried out or presented during the past ten years is included. The overarching objective is to highlight gaps in knowledge and to help steer future research in structural fire engineering, particularly experimental research at the large-scale.

“…Under high temperatures, r.c. frame members undergo degradation of material properties [1], weakening steel reinforcement and concrete, stiffness [2,3], produced by spalling of concrete on the sides exposed to fire, and ultimate ductility [4,5], with a reduction in the frame members exposed to fire on three and four sides and an increase on the bottom side of beams due to fire-reduced yield strength of the longitudinal bars in tension. Moreover, mechanical and geometrical properties of HDLRBs and LRBs are reduced when temperatures exceed the point at which vulcanization between layers of rubber and steel plates occurs [6].…”

“…The information is used to simulate a more realistic fire. Fire resistance of the structural members is then calculated (Franssen et al, 2009;Kodur et al, 2012), and expressed as the time up to which the structural integrity is maintained against the applied fire loads (Kodur and Dwaikat, 2007).…”

2Post-earthquake fire (PEF) contributes significantly to loss of life and property following large earthquakes in urban regions. In the absence of adequate PEF provisions in the codes and criteria, an investigation is performed on a reinforced concrete portal frame, divided into two unequal parts by a firewall. Acknowledging that firewalls could break down after earthquake, three fire exposure scenarios are assumed: only the left part exposed, only the right part exposed and the entire frame exposed. In the first two scenarios, the firewall remains intact, whereas in the third it is assumed to be broken down. The building is first pushed to displacement corresponding to the life safety level of performance based on FEMA 356 code. Then, using a natural fire curve, fire analysis is performed. Fire-alone analysis is performed to provide a point of reference. No failure occurs in any of the fire-alone scenarios, or when exposing the smaller part of the building to the PEF. In contrast, exposing the larger part and the entire frame to PEF makes the frame fail at around 50 min and 25 min, respectively. This shows the importance of firewalls to reduce vulnerability of reinforced concrete buildings in case of PEF. The approach used allows designers to choose the position and configuration of firewalls to best protect a building against PEF.
