The current local stability criteria (KBC2009, AISC2010) are enacted through theoretical and experimental studies of ordinary steels, but the mechanical properties of high strength steels are different from ordinary steels. The high strength steel in the applicability of design criteria should be needed to review because of increasing market demanding for high strength steel in the high-rise and long span buildings. In this study, stub columns of H-shaped and box section with various steel grades subjected to concentric loading were investigated, and these steels were checked to the applicability of current local stability criteria. The difference between the ordinary steel and high strength steel was compared. As a result of comparison with various steel grades, most specimens were satisfied with the design criteria, but some specimens with lower tensile strength were not reached the required strength. It is considered that the uncertainty of material was the higher when the tensile strength of material was the lower.

“…Since developed, the structural performance of SM 570 was evaluated by an experimental method and an analysis. Researches focused on evaluation of material properties and structural stability at joints between column and beam [1][2]. After this structure performance related research, many high-rise buildings and structures using the SM 570 into columns and beam were constructed in Korea.…”

Material strength is one of the most important factors in designing a building. For this reason, many structural steel manufacturers have been trying to develop it. In Korea, SM 570 is one high structural steel that has many merits such as longer span and reduction of construction cost for steel works. However, the fire resistance performance of H-section made of SM 570 has not been evaluated. Especially, in high-rise steel building that can be built with various joint systems like hinged to hinge, hinge to fixed, and fixed to fixed. However, the performance of fire resistant is limited. In this paper, to evaluate the fire resistance of H-section made of SM 570, the advanced fire design was conducted using regressive equation of the mechanical and thermal properties at high temperature, compared with those made of an ordinary structural steel, SS 400. The facts show that hinge to hinge had the lowest load bearing capacity at high temperature. Therefore, to keep the same fire resistance with other types boundary conditions, the more passive fire materials are required.
