During a fire a structural member may be exposed to heating at extremely high temperatures, and as a consequence its strength may decrease substantially in a short time. To prevent such loss of strength it is essential to protect the member against excessive temperature rise. One of the problems in selecting appropriate protection is the evaluation of its effect on the fire performance of the member. Usually fire performance is determined by subjecting a member to a standard fire. In practice, however, the severity of fire conditions can vary over a wide range. The influence of fire severity on the fire performance of steel members, as well as the influence of other important factors that determine their fire resistance, are examined.
