Abstract Under axial compression, the present article analyses and compares behaviour of Plain Concrete filled Nano Silica modified concrete with light gauge steel rectangular columns. In 18 work samples, plain nano silica-modified was tested on sections. Investigations were conducted into several essential variables, including geometry cross-section, tubular thickness steel, depth-to-thickness...

Abstract Recently, aluminium alloys are extensively used in the construction sector because of their small self-weight, good corrosion resistance, low maintenance, high recyclability, and aesthetic appearance. However, one main disadvantages these is Young’s modulus, which may cause a stability issue structural members. Moreover, currently available design standards for predicting buckling resi...

The energy absorption of concrete filled, hollow-steel bracing was analyzed respect to geometric and mechanical parameters including the width-to-thickness section ratio, slenderness level, and strength of the steel and concrete. Local buckling and ductility were also investigated with respect to variation in the cross-section. The infill increased the compression resistance, even after multipl...

The chord length is an essential geometric property that must be defined in the analysis of isolated joints composed hollow steel sections, as well boundary conditions test. these parameters’ effect on behavior has been addressed by other studies, mostly with between circular sections compact or semi-compact cross-sections. Recent research about tubular cases slender where design containing sti...

Despite substantial progress in recent years to improve the design guidance for high strength steel (HSS) structural elements, this has mainly been ambient conditions with their fire response still need of further research. Accordingly, paper reports on an investigation into performance unprotected HSS hollow section columns fire. Finite element models made from square, circular and rectangular...

Abstract The calculation of the loadbearing capacity hollow section joints using design formulas according to EN 1993‐1‐8 assumes full‐strength welded connections if non‐linear stress distribution over circumference is not covered by calculation. Sufficient ductility in ensures a plastic redistribution within each joint. In case structures made high‐strength steels, it becomes more difficult me...

Stainless steel offers a range of benefits over conventional carbon in structural applications. This paper presents the detailed numerical modelling shear response cold-formed stainless hollow flange sections using finite element software package, Abaqus. The effect geometric parameters such as section height and thickness, influence different grades were investigated following validation model...

The optimisation of the design method for verification slender steel beam-columns is still a current issue not only from scientific point view, but also practice. Therefore, main objective this paper comparison suitability established approaches, according to European standards and aluminium structures, on basis numerical simulations. Thus, finite element model was validated experimental analys...
