Steel joists are economical and efficient structural assemblies usually designed to transfer the load imposed on roofs or floor decks to structural frames. In many applications, steel joists are required to provide fire resistance for a given interval; therefore, they are either protected by fire-resistant membranes (e.g. ceiling) or fire-resistant materials (e.g. intumescent coating). Currently, the amount of time a steel joist is able to withstand the effects of fire (i.e. fire rating) is determined experimentally by testing conventional steel joist configurations subjected to a standard time-temperature curve known as the ASTM E119 standard fire.
