Steel framed building can be destroyed due to deteriation of structural stabilities in a fire. This leads a TMC Fire Resistant Steels and this study analyzed the structural stabilities such as a deflection and a reduction of maximum load capacity for the structural beams built with a TMC Fire Resistant Steel. In this study the structural stabilities were evaluated using a mechanical properties in high temperatures not only a heat transfer theory but a heat stress anlaysis with a statistically determinated beam and a statistially indeternated one. The results showed that a TMC Fire Resistant Steels demonstrated a little lower those of Fire Resistant Steels.

Fire is very serious condition in steel based structures. Therefore, to enhance the structural stability of columns and beams in high temperatures, fire resistant steels and TMC fire resistant steels are developed from steel manufacturing companies. In this study to evaluate the structural stability and compare the resistant performance, a fire engineering design method was applied and fire resistant steels showed the better performance than other two materials.

A fire-resistant steel with enhanced load-bearing capacity has been developed to enable structural elements such as columns and beams withstand exposure to severe fire conditions. To precisely evaluate the fire-resistant performance of structural elements that compose fire-resistant steels, mechanical properties such as yield strength and elastic modulus are essential. To obtain the mechanical database of fire-resistant steels at high temperatures, tensile tests at high temperatures were conducted on steels of two kinds of thicknesses. The results showed that the thickness difference could not affect the mechanical properties at a high temperature.

Performance has been developed in terms of structural strength. Especially, in a structural steels, it is regarded as a common design process that an yield stress of thicker plate than 40mm uses that of below 40mm in thickness. This can be done using TMCP(Thermo mechanical control process). In this study, the structural stabilities such as deflection, maximum load carrying capacity would be calculated in high temperatures.
