Recently, building constructions have been developed toward high-rise, long span, and multi-complexed using the high strength materials, optimized section. But the structural behavior of steel structural members built with a high strength steel at fire condition is not clarified because of lacking of information of related references such as mechanical and thermal properties at high temperature situation. In this paper, to evaluate the structural stability of member or frame of steel framed building at fire situation through the engineering method, the mechanical and thermal experimental coupon tests have conducted at various high temperatures and the comparison to those of ordinary strength steels were done.

“…When compared with conventional steel, structures built using HSS offer advantages in increased strength and reduced weight, which could lead to economy in construction. As a result, research on the behavior and application of HSS has become an important topic in the structural engineering community [2][3][4][5].…”

Fire-resistant and high temperature behavior of high strength steels (HSS) for structural engineering applications has become an important research topic in recent years. In this paper, a succinct review of HSS behavior under and after high temperature exposure is provided. The review addresses the following aspects of HSS: (1) their mechanical properties under and after fire exposure, (2) residual stress in welded HSS sections, and (3) high temperature performance of HSS columns. Recent studies have demonstrated that different grades of HSS can exhibit noticeable differences in their mechanical properties under and after fire exposure, and different cooling methods could have an effect on the post-fire mechanical properties of HSS. Because current design standards for steel structures under elevated temperature were developed based on mild steel, care must be exercised when applying these standards to HSS as they are not necessarily applicable.

“…The strain rate range used for testing is usually restricted to approximately 0.00025-0.0025s -1 , and the codified stress rate range is between 6-60 MPas -1 [2]. Tests under transient heating conditions are also conducted using constant heating rates in the range 5-20°C/min, with 10°C/min being more frequently used than others in generating stress-strain models which are deemed to include creep implicitly [3,4].…”
