Unprotected steel and structures exposed to the atmosphere inevitably corrode. For thin-gauged especially, corrosion is critical for stability. Although reduction in thickness caused by insignificant some structures, other unacceptable. Therefore, protection a crucial issue industry. Over last decades, many new systems innovative products have been introduced onto market. Corrosion cold-formed ...

The objective of this paper is to provide work towards design methods to predict both the loss of stiffness and the available ductility for cold-formed steel members subject to cross-section deformations resulting from local and distortional buckling. Existing design specifications provide some guidance on how to predict the stiffness of cold-formed steel members, but no guidance on their avail...

A series of tests on cold-formed steel foamed concrete (CSFC) composite walls subjected to axial load were proposed. The primary purpose of the experiments was to study the mechanical behavior and identify the failure modes of CSFC composite walls. Two main factors were considered in this study: 1) specimen with pouring foamed concrete or without and 2) different foamed concrete density ranks (...

the formation of nano/ultrafine grained ferrite in low carbon steels containing different amounts of niobiumwas investigated using thermomechanical treatment which consisted of annealing of 85% cold rolled martensite with different parameters. the specimens were characterized by optical and scanning electron microscopy and vickers hardness test. a lamellar dislocation cell structure was formed ...

Abstract This paper presents the results of a theoretical-numerical study laterally-restrained thin-walled steel rectangular hollow flange beams subjected to bending, shear and bending interaction. Finite element analyses were carried out by using ANSYS software, validated previous experimental tests. Furthermore, effect intermediate stiffeners was investigated, where improvement percentage in ...
