A hollow steel box column that satisfies the requirements of a highly ductile member of AISC Seismic Provisions [1] can develop good seismic performance. The addition of concrete infill inside a hollow steel box column, a so-called concrete-filled box column (CFBC), might delay or decrease buckling of a steel box column so that, for a highly ductile . As high strength steel (HSS) box columns are often fabricated by welding of steel plates together, welding process during fabrication inevitably introduces residual stresses in the columns and affects their strengths.Hence, a good understanding of the influence of the welding process on the residual stresses of HSS built-up box column is important for the design of . “Composite columns are structural members, which are subjected mainly to axial compressive forces and end moments. The general term ’composite column’ refers to any compression member in which the steel element acts compositely with the concrete element so that both elements contribute to the strength” Oehlers and Bradford [1].

Strength of slender concrete filled high strength steel box columns
High strength steel box columns are desirable in the base columns of a tall building where the ratio of axial stress to bending stress is high and the cross-section is virtually a member in axial compression. These generally result in fairly large cross sections. This section outlines the design of short high strength steel concrete filled box . Experimental and analytical studies on high strength steel box columns infilled with normal strength concrete have been conducted by Uy [2], [3].The obtained results were compared with the Eurocode 4 (EC4) approach which limits the maximum yield stress of steels to 460 MPa and compressive strengths of concrete to 60 MPa.It was shown that EC4 overestimated the . A parametric study on high strength steel box and I-section columns at elevated temperatures has been performed using the developed finite element model.
