ABSTRACT
In the Tabular methods the design tables are relatively restrictive but cover common cases of design. The tabular method and the simple calculation method are used only for specific types of members under prescribed situations. The tabular method and the simple calculation method are used only for specific types of members under prescribed situations. The temperature distribution is assumed to be the same over the full length. An alternative method to the use of the standard fire curve is to model a natural fire on the basis of a parametric temperature–time curve. The fire resistance of steel-reinforced concrete (SRC) members is based on the strength reduction of steel, which depends on the concrete cover. The concept of load level is very important in fire design. Composite columns always have a higher fire resistance than steel columns, taking advantage of the thermal properties of concrete. In addition, the reinforcement also contributes to fire resistance.
