Abstract null null In recent years, concrete-filled steel tubular (CFST) columns are increasingly used in ocean construction, such as offshore towers and marine platforms. When used in harsh marine environments, the inevitable pitting corrosion poses a crucial threat to the outer surface of CFST and results in stress concentration, early local buckling as well as confinement reduction towards concrete. Relevant study is rarely seen given the complexity in experimental realization and numerical m...

Abstract null null The fracture of layered rocks subjected to tensile stress is involved in various subsurface energy-related activities. Many studies have numerically investigated the fracture evolution behaviour and Brazilian tensile strength (BTS) of layered rock in Brazilian tests. However, the fracture mechanism of layered rocks, especially those with interbedded hard-soft layers, is still not well understood. This is mainly due to the fact that the layered rocks were often modelled as two-...

Abstract null null This paper proposes a novel design of a corner-supported steel-concrete composite module that is suitable for multi-storey modular buildings. The strength and stiffness of the individual modules are improved through the designs of concrete-filled steel tubular (CFST) columns, laminated double beams, and integrated concrete slabs. The overall structural integrity of the modular buildings is improved through the designs of tenon-connected inter-module connections combined with b...

Abstract null null When a concrete-filled steel tube (CFST) is used in offshore construction such as electricity towers, bridges or platforms, it is subjected to continuous degradation during its service life due to the long-term in-service actions and the ocean corrosive environment. Fibre reinforced polymer (FRP) strengthening makes an effective solution to extending the service life of corroded CFST columns in existing offshore structures. For the rational design and tactful application of th...

Abstract null null Evolution of microstructure and texture in nanocrystalline (nc) face-centered cubic materials subjected to high-strain-rate compression are investigated. Three nc materials, differing in grain size or stacking fault energy, namely, 27 nm Ni, 70 nm Ni, and a 27 nm NiCo alloy are deformed under high strain rates (8000-23000 s−1) using the split-Hopkinson pressure bar technique. The transmission Kikuchi diffraction technique and discrete-crystal plasticity finite element (D-CPFE)...

Abstract null null The residual stress and the dimensional distortion due to rapid temperature variation during the welding process are often crucial for the life-cycle behavior of structures, especially for key connection regions in offshore and marine applications. This paper evaluates the detailed welding effects on the strength and stiffness of concrete-filled steel tubular (CFST) Y- and K-joints using advanced finite element modeling (FEM), and the results are then validated and compared wi...

Abstract A lot of countries are experiencing freshwater crises due to the increasing growth of the population together with the infrastructure development that is aligned with the needs of fresh water. There are also deficiencies in freshwater in many coastal areas where seawater is more accessible. To reduce unnecessary resource-wasting and meanwhile drive sustainable development in the construction industry, great efforts have been made to utilize seawater as the alternative mixing water for c...

Abstract In this paper, a dynamic recrystallisation (DRX) viscoplastic self-consistent (VPSC) model is created to predict the continuous DRX (CDRX) and twin-assisted DRX (TDRX) behaviour within an AZ31 magnesium (Mg) alloy over temperatures ranging from 25 °C to 200 °C. At this temperature range, the active deformation mechanisms and physical phenomena participating in the strain accommodation and texture evolution of Mg alloys are: a basal slip, a prismatic slip, c + a pyramidal slip, { 10 1 ¯ ...
