The behaviour of cold-formed normal- and high-strength steel columns with square rectangular hollow sections (SHSs RHSs) at elevated temperatures was investigated numerically in this paper. A finite element model developed validated against experimental results for the SHS RHS stub long tested ambient temperatures. Parametric studies were subsequently conduced on various cross-section slenderne...

Abstract Wire Arc Additive Manufacturing (WAAM) has the potential to produce free form metallic structures, suitable for use in construction industry, and so is currently being rapidly developed by structural engineers. This paper details an experimental program investigating stability performance of ten WAAM 316L stainless steel square hollow section stub columns with varying cross‐sectional s...

sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. but square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

While active fiber composites (AFC) based upon solid cross-section piezoelectric fibers are very useful for anisotropic activation of composites, they require high voltages and are constrained to non-conductive matrix materials. AFC’s based upon hollow cross-section piezoelectric fibers have shown promise to lower operating voltages and broaden the choice of possible matrix materials. This pape...
