Directions in structural‐fire safety design for steel buildingsa

Abstract Fire safety considerations have an impact on the design of almost all structures, ranging from small residential structures to high‐rise buildings. One important aspect of building fire safety is structural‐fire safety, with the goal of preventing or delaying collapse of structures during severe fires. Structural‐fire safety is of particular importance for steel structures, because of the high thermal conductivity of steel. Structural‐fire safety design is most often accomplished using non‐engineered prescriptive approaches. However, there is increasing interest in engineered structural‐fire safety design for potential advantages in safety, economy and design flexibility. This paper provides an overview of engineered structural‐fire safety design for steel buildings, and discusses some of the challenges in this field.
