DEFORMATION CAPACITY OF WELDED SQUARE HOLLOW SECTION MEMBERS MADE OF HIGH STRENGTH STEEL GOVERNED BY LOCAL BUCKLING

Concrete filled steel tube has been consistently used in tall buildings as it represents excellent structural performance and economical efficiency compared with other structural systems. The use of high strength steel in concrete filled steel tube can reduce the column size and increase the effective space in the buildings. But, the limit of width-to-thickness ratio to prevent local buckling is an obstacle to applying the high strength steel as it considerably decrease following to the strength increase. This paper addresses the effect of steel plate slenderness limit on the compression behavior in 800 MPa Grade steel. Four short column specimens were tested under axial compression. Main test variables were width-to-thickness ratio and shape of section. Test results were analyzed in the viewpoint of local buckling strength, yield strength, maximum strength and plastic deformation capacity of specimens. The experimental results showed that all specimens exceeded the maximum strength of calculated value by design code and represented similar deformation capacity regardless of width-to-thickness ratio. So, the limit of width-to-thickness ratio in high strength steel could be amended less strict.

Force Characteristics

A new version of steel and reinforced concrete (SRC) structural system is proposed. It consists of H-shaped high strength steel, concrete and hoop reinforcement. Longitudinal reinforcement is not used. Experiments were carried out to study the restoring force characteristics of the proposed SRC, with emphasis on the effects of hoop reinforcement. Hoop reinforcement improved the compressive behaviour of the concrete and protected the H-shaped steel from local buckling. The proposed SRC system showed a large energy dissipating capacity as well as a large deformation capacity.

Steel Strength

High strength steel sections have been increasingly used in buildings and bridges, and steel angles have also been widely used in many steel structures, especially in transmission towers and long span trusses. However, high strength steel exhibits mechanical properties that are quite different from ordinary strength steel, and hence, the local buckling behavior of steel equal angle members under axial compression varies with the steel strength. However, there is a lack of research on the relationship of the local buckling behavior of steel equal angle members under axial compression with the steel strength. A finite element model is developed in this paper to analyze the local buckling behavior of steel equal angle members under axial compression, and study its relationship with the steel strength and the width-to-thickness ratio of the angle leg. The finite element analysis (FEA) results are compared with the corresponding design method in the American code AISC 360-05, which provides a reference for the related design.
