Fire-resistant steels: Fire-resistant steels can improve the resistance of buildings to the various consequences of fires

摘要

Today, steel structural members are protected from fire by the addition of insulating coatings or encasement. The potential benefits of reducing or even eliminating fire protection coatings with fire-resistant steels that provide effective high-temperature strength would drive down construction costs. This article describes work in which some important classes of microalloyed steels were evaluated for fire-resistance properties. The two steps to the experimental design were to develop a methodology for testing uncoated structural materials for fire-resistance, and to examine elevated temperature properties of selected steels.
