Abstract: This investigation delves into the impact of temperature and tensile strain rate on the mechanical characteristics of high-strength Q960 steel. The inherent strength and stiffness properties of steel undergo degradation ...

Abstract: This paper presents the effect of temperature and tensile-strain rate on the mechanical properties of high-strength low-alloy structural Q460 steel. Standard coupon tensile tests were carried out to obtain the stress-strain ...

Abstract: To better understand the mechanical behavior of cold-formed steel (CFS) quadruple-limb built-up box-section (QBB) columns associated with flexural buckling, 12 axial compression tests with different slenderness ratios and ...

Abstract: The objective of this paper is to to ascertain the reliable mechanical properties of cold-formed Q345 steel at elevated temperatures while considerting the effects of tensile strain rate and specimen width. This paper ...

Abstract: High-strength steels are finding wide applications in steel-framed buildings. Therefore, fire resistance design of high-strength steel structures has gained more attention in recent years. Rapid reduction in mechanical ...
