In the seismic design of reinforced concrete moment-resisting frame (RC MRF) structures equipped with steel damper columns (SDCs), design criteria should consider both peak responses (e.g., story drift) and cumulative re...

This paper presents an experimental investigation on the behavior of steel fiber reinforced concrete deep beams at elevated temperature. Twelve reinforced concrete deep beams were cast and tested. The beams were tested u...

The corrosion behavior of two wrought super duplex stainless steels (SDSS), UNS S32750 and UNS S32760, and a cast duplex stainless steel (DSS), DIN/EN 1.4517, was evaluated in 3.5 wt% NaCl and ASTM D1141 synthetic seaw...

Lean duplex stainless steels (LDSS) emerged as a competitive duplex stainless steels (DSS) where Ni is partially replaced by lower cost alloying elements such as Mn and N. However, to date there has been little to no inf...

Abstract The uncontrolled floor heave in gob-side entry retaining is the serious problem of underground coal mining. This phenomenon has gravely restricted the application of pillarless mining that has been increasingly ...

For the X80 pipeline steel, electrochemical impedance spectroscopy and potentiodynamic polarization curves were employed to examine the electrochemical corrosion behaviors of its base metal and weld joint under varying t...

Steel fiber (SF) cement mortar, renowned for its dual advantages of strength and toughness, is widely used in construction, transportation, and other engineering fields. However, in actual service, it often faces challen...

Industrial symbiosis offers a critical pathway for advancing resource circularity and energy efficiency in hard-to-abate sectors. As the steel and cement industries undergo profound structural transformation toward low-c...

Duplex stainless steels fabricated by Laser Bed Powder Fusion (LPBF) exhibit refined and metastable microstructures that can be particularly sensitive to intermediate-temperature exposure. In this study, the effect of 47...

Abstract The current paper is based on a case study conducted at an industrial facility in Egypt, which is responsible for processing greenhouse structures. Steel tie rods play a vital role, as they prevent the truss fra...

Abstract Accurate estimation of the shear capacity of steel fiber reinforced concrete (SFRC) beams without stirrups remains challenging because the response is governed by strongly coupled geometric, material, and reinfo...

Localized corrosion in laser–arc hybrid welded high-nitrogen steel joints is strongly affected by microstructural heterogeneity. This study focused on the effect of welding speed on dendritic connectivity and the corre...

The increased focus on the reduction of greenhouse gas emissions in the building and construction sector has heightened the demand for structural systems that reduce both material and embodied carbon. Pre-engineered buil...

The microstructure evolution and performance characteristics of the heat-affected zone (HAZ) in laser welding of 10Ni5CrMoV steel are investigated. By designing novel thermal simulation specimens and utilizing a thermal ...

Abstract The enhancement of durable and environmentally friendly superhydrophobic (SHP) coatings for metal protection remains a significant challenge. This study presents a green and effective strategy for fabricating a ...

Abstract Natural materials (NMs) have emerged as better alternatives for the mitigation of corrosion of metals. NMs can be used as both inhibitors and coatings; however, they have been used mostly as inhibitors. In this ...

Abstract CO2 curing can greatly enhance the properties of concrete while actively sequestering CO2. However, the influencing mechanisms of CO2 curing on the passivation film of steel bars in concrete remains unclear. In ...

We demonstrate how controlling the heat affected zone during laser powder bed fusion may be used to optimise the phase composition of additively manufactured (AM) components in-situ to reduce post-processing heat treatme...

With the continuous improvement of lightweight requirements for equipment, Mg alloys are increasingly widely used, and their joining with traditional steel materials is essential. However, Mg and Fe have almost no solid ...

Reducing embodied carbon in the built environment requires reliable methods to assess structural materials, particularly steel, one of the most carbon-intensive. While environmental product declarations (EPDs) provide st...

Abstract The vortex-induced vibration (VIV) characteristics of a long-span twin continuous steel box girder bridge under varying wind angles of attack (α m ), Scruton numbers (Sc), heights of beam (D = 0.078 m, 0.108 m,...

Abstract In this work, the formation and evolution of the rust layer on coarse-grained (25.0 µm) and ultrafine-grained (0.5 µm) weathering steels were investigated through wet/dry cyclic corrosion test in 3.5 wt%...
