In this paper, a numerical investigation on the global buckling capacity of axially compressed steel columns with hot-rolled I cross-section at elevated temperatures is presented. Geometrically and materially non-linear finite element model ABAQUS software were used to determine resistance. The was validated using experimental results available in literature, then generate database load-carryin...

Abstract This paper presents numerical simulations on the behavior of thin‐walled steel tubular bridge piers box sections under cyclic lateral loading in presence constant axial compression loads, using three‐dimensional finite element analysis adopted commercial computer software ABAQUS. The and experimental results are compared to show how material models, such as elastic perfectly plastic (E...

A parametric optimization problem of cross-sectional sizes for cold-formed steel lipped channel structural members subjected to axial compression has been considered by the paper. An is formulated as define optimum member taking into account post-buckling behavior (web and flange local distortional buckling) well requirements when profile perimeter (strip width), thickness, design lengths mater...

Glass fibre reinforced polymer (GFRP) profiles are finding increasing applications in civil engineering structures, owing to the several advantages they offer over traditional materials. However, due to the combustible nature of their polymer matrix, there are well-founded concerns about their behaviour at elevated temperature and under exposure to fire. These concerns are hindering the widespr...

C and Z sections are two of the most common cold-formed steel shapes in use today. Accurate prediction of the bending performance of these sections is important for reliable and efficient cold-formed steel structures. Recent analytical work has highlighted discontinuities and inconsistencies in the American Iron and Steel Institute ~AISI! and Canadian Standards Association ~S136! design provisi...
