Single Storey Steel Buildings Exposed to Localised Fires

2019

The most commonly built single storey buildings for commercial purposes in Sweden are made of steel structures consisting of steel trusses supported by steel tubular columns as the main load bearing system. The building envelop consist of corrugated steel sheeting and walls made of sandwich panels. The fire regulations for these types of buildings generally require that at least 30 min of fire resistance time for the main load bearing structural components. However, some ambiguity regarding the interpretation of the rules persists, which results in many cases with the trusses having not been provided with any fire protection. The study presented here intended to analyse the ‘real performance’ of these types of buildings in localized fire situations and propose a simplified design procedure that can satisfactorily predict the behaviour of the structure subjected to localized fire. An extensive finite element analysis was performed for this purpose. 1 Research Assistant. Division of S...
