Special Issue Information

Dear Colleagues,

Steel structures are widely used in modern land and marine engineering due to their high strength, excellent ductility, and sustainability. With the trends of material optimization, structural lightweighting, and the demands of complex environments such as offshore engineering, research on steel structures has expanded into broader areas.

This Special Issue, titled “Advanced Research in Steel Structures,” aims to gather the latest advances in both land-based and marine steel structures, covering multiple aspects such as structural performance, new material applications, development of innovative structural forms, and advancements in design methods. Topics of interest include, but are not limited to, the following: strength, stability, and fatigue performance of steel structures under static, dynamic, and extreme loads (e.g., wind, waves, earthquakes); corrosion protection and durability of steel structures in marine environments; soil-structure interaction of steel foundations and seabeds; and applications of new steel structural systems such as prefabricated and composite structures. By promoting the integration of advanced analysis, intelligent monitoring, and engineering design, this Special Issue intends to support safer, more economical, and more sustainable applications of steel structures in both terrestrial and marine engineering.

Abstract
Buckling-restrained braces (BRBs) are widely used to improve the seismic performance of high-rise and long-span structures. This study proposes a triple-tube GFRP–steel buckling-restrained brace (TTGS-BRB) as a lightweight and corrosion-resistant energy-dissipating member for such structures. To investigate its hysteretic behavior, pseudo-static tests were [...] Read more.
Buckling-restrained braces (BRBs) are widely used to improve the seismic performance of high-rise and long-span structures. This study proposes a triple-tube GFRP–steel buckling-restrained brace (TTGS-BRB) as a lightweight and corrosion-resistant energy-dissipating member for such structures. To investigate its hysteretic behavior, pseudo-static tests were conducted on two scaled TTGS-BRB specimens with different wrapping orientations and end details, and a finite element model was established and validated against the test results for further parametric analyses. The test results showed that the specimen with the ±30° wrapping configuration and end stiffeners exhibited better hysteretic performance than the 90° specimen without end stiffeners, with the yield force increasing from 147.98 kN to 161.68 kN, the cumulative plastic deformation (CPD) increasing from 7.49 to 209.56, and the cumulative plastic energy (CPE) increasing from 5.25 to 199.12. Based on the validated finite element model, the effects of fiber wrapping orientation, end stiffeners, interfacial gap, Pcr/Py ratio, and steel tube diameter-to-thickness ratio on the hysteretic performance of full-scale TTGS-BRBs were systematically investigated. The numerical results indicate that wrapping orientations within the range of ±0° to ±45°, end stiffening at both ends, an interfacial gap of 1.5 mm between GFRP and steel, an appropriate Pcr/Py ratio, and a steel tube diameter-to-thickness ratio of less than 24 are beneficial for improving the hysteretic performance of TTGS-BRBs. These findings provide useful references for the design and application of TTGS-BRBs in practical engineering. Full article

Suction anchors are widely used in offshore wind power foundations, where their penetration behavior critically influences installation efficiency and safety. Existing studies mainly focus on homogeneous soils, while the mechanisms of suction-assisted penetration in layered seabed remain less understood. This study establishes a numerical model based on the Material Point Method (MPM) to simulate suction anchor penetration in saturated soils, accounting for large deformations and hydro-mechanical coupling. The model is validated against physical tests, confirming the reliability of MPM. A series of simulations is conducted to examine penetration behavior under layered conditions, emphasizing the effects of stratigraphic sequence and configuration, including sand-over-clay (SC), clay-over-sand (CS), sand–clay–sand (SCS), and clay–sand–clay (CSC) profiles. The analysis reveals complex mechanical responses during penetration, including excess pore water pressure, soil displacement, effective stress, and penetration resistance. The results demonstrate that penetration behavior is governed by both the stratification sequence and the number of soil layers. Overall, this study clarifies the complex mechanical responses of suction caissons in layered soils, verifies the suitability of MPM for simulating large-deformation and hydro-mechanical coupling problems, and provides insights for the design and safe installation of suction caissons in stratified seabeds.
