A review of research on high-strength steel structures

Abstract

Structures made using high-strength steel (HSS) offer numerous benefits in terms of mechanical performance, economy and sustainability. With such structures increasingly being used in practice, academia in civil engineering is progressively focusing on HSS structures through experimental, numerical and theoretical investigations. This paper reviews research advances in HSS structures at the level of material properties, the behaviour of component members and connections and the performance of frame structures, and the corresponding findings are summarised and discussed. The literature indicates that, compared with structures made with conventional mild steel, HSS structures exhibit new features in terms of mechanical performance. It is hoped that this review will be helpful in providing a better understanding of the mechanism of HSS structures subjected to static or cyclic loading and promoting their practical application.

Tensile behaviour of S690QL and S960QL under high strain rate

“…Studies [7,[22][23][24][25][26][27] show that the application of high Y/T ratio in HSSS has been successful in some bridge and building applications but limited in other engineering applications (especially offshore applications) due to the lack of characterisation data on their structural performance. Although the Y/T ratio only becomes relevant in the post-yield behaviour of steels, which represents the ability to withstand plastic loading and basic measure of deformation capacity, other related characteristics such as strain-hardening exponent, ductile tearing resistance, and overall global deformation are important factors to consider when considering the practicality of using high Y/T ratio as a measure of plastic strain capacity of cracked components [23].…”

“…Compared with other published data and experimental results from conventional low strength carbon steel tensile tests, modern high strength steel possesses a different stress-strain characteristic, reduced elongation and low strain-hardening capacity and, generally, has high Y/T ratio [6,7]. In addition, very little information is available on the performance of HSSS (specifically, with Y/T in excess of 0.90) subjected to high loading rate scenarios.…”

Ductile damage model calibration for high-strength structural steels

“…and engineering equipment (engineering vehicles, crane facilities, etc.) [1][2][3][4]. Application of HSS has the potential to reduce plate thickness in welded structures for saving welding costs and to support much higher external loads for realizing more innovative structures.…”

Literature Review: Concrete Filled Steel Tubes Under Transverse Impact Loading

“…Furthermore, Le Hoang & Fehling [134] presented the influence of steel fiber content and aspect ratio on the uniaxial tensile and compressive behavior of ultra-high-performance concrete.…”
