ABSTRACT

Many authors studied risk assessment (RA) of civil infrastructures in an MH environment. For example, one potential method for assessing MH risk is to assess affinities between hazards. Structural failures due to fire following hazards such as earthquakes and blast have been observed in the past. This can lead to progressive collapse of the structure or has the potential to reduce the time available for evacuation operations posing a threat to occupants. Thus, there are several studies in the literature on analysis of structures that have been damaged by an extreme event followed by fire. With an intent to raise awareness of this potential life-threatening issue, Quiel and Garlock (2010) studied the effects of fire following an extreme event (i.e., blast or impact) that causes failure of one column on the perimeter of a common steel building frame, designed to satisfy new U.S. Department of Defense (DoD) guidelines. The study assumes that the extreme event not only damages one column but also damages active fire protection (i.e., sprinklers) near the structural damage. They used a multihazard approach similar to those of Della Corte et al. (2003) and Chen and Liew (2005), where performance of the structure is investigated under fire after it had sustained damage due to the primary hazard.
