Local Buckling Behaviors of Built-Up Box Columns Fabricated with High-Performance Steel under Concentric Axial Loading

Abstract:

Recently, high-performance steel has been increasingly used for structural materials in buildings and bridges with the demand for high-rise and long-span of main structures. This paper is a series of basic study for the design specification of structural members using high performance steel, material properties of HAS800(High-performance rolled Steel for building structures). HSA800 was compared with the requirements of Korean Standards(KS). Built-up box stub columns with variables of width-to-thickness ratios are planned in order to investigate the local buckling behaviors and check the current design limit of width-to-thickness ratio. In addition, the buckling behaviors of stub columns obtained finite element analysis were compared with those of test results.
