Structural Fire Safety - As exemplified by a Swedish Manual for Analytical Design

Research output: Book/ReportReport

Abstract

During the last decade, a rapid progress has been made in the development of validated analytical models for the thermal and mechanica1 behaviour of fire exposed structures and structural members. In a long-term perspective, the development now goes towards an analytical design, directly based on a natural fire exposure and specified with respect to the combustion characteristics of the fire load and the geometrical,ventilation, and thermal properties of the fire compartment. Internationally, the development then includes a probabilistic approach, based either on a system of partial safety coefficients or the safety index concept. The paper describes the basic characteristics of an analytical method for a structural fire engineering design starting from the natural fire exposure and related to the semi-probabilistic approach via partial safety coefficients. The consequences of a structural failure are considered by dividing the structures or structural members into categories with a differentiation with regard to the design fire load density and length of fire exposure. The application is briefly exemplified on the basis of a Swedish manual, in preparation, for fire exposed reinforced concrete structures .
