New Buckling Curve for a Compressed Member with Cold-Formed Channel Cross-Section

Buildings
The verification of a column made from a lipped cold-formed channel section, subjected to pure axial compression relative to the gross cross-section, often results in a combined verification of bending and compression due to the appearance of a shift of ...

Stability and Plasticity Interaction Effects in Basic and Building‐Size Steel Sway Structures

ce/papers, Volume 8, Issue 6, Page 578-583, December 2025.
Abstract Accurate design rules are crucial for the safety, sustainability, and economy of steel structures. To predict the load‐bearing capacity of sway structures, Eurocode 3, Part 1‐1, uses individual member unity checks, which are assumed to include the interaction between members, related to their stability and plastic behaviour.

Calibration of Equivalent Imperfections for Second Order Theory Analysis of Hot‐Rolled U‐sections

ce/papers, Volume 8, Issue 6, Page 626-631, December 2025.
Abstract The stability behavior of steel structures is important when performing design. Standards (such as EN 1993‐1‐1 – Eurocode 3 Part 1‐1) take the stability of steel members into account and allow for verifications using reduction factors or by second order theory analysis considering equivalent geometric imperfections.

Design Suggestions for I‐Shaped Knee Connections with Conditional Variational Autoencoder

ce/papers, Volume 8, Issue 6, Page 513-518, December 2025.
Abstract Conditional variational autoencoder (CVAE) are used throughout the literature in the sense of performance‐based generative design. One main advantage is the possibility of an inverse problem formulation, allowing the exploration of design possibilities/variations.

Structural Performance and Weight-Efficiency Trade-Offs of Bulb and Angle Stiffeners in Imperfection-Sensitive Plate Buckling and Collapse

Journal of Marine Science and Engineering
This study presents a mechanics-based comparison of the buckling and ultimate strength behavior of stiffened plates reinforced with bulb-type and built-in angle stiffeners, with particular emphasis on the trade-off between structural performance and ...

Stability verification of frames with web tapered members and slender sections

ce/papers, Volume 8, Issue 6, Page 640-645, December 2025.
Abstract This work presents a comprehensive parametric study using material and geometric non‐linear analyses that included the effect of imperfections (GMNIA) to determine the collapse loads of realistic frames with web tapered members and slender sections (Class 4).

Fire Resistance of Ultra-High-Strength Steel Columns Using Different Heating Rates

Applied Sciences
Ultra-High-Strength Steel (UHSS) offers several advantages over normal carbon steel, promoting exceptional strength, reducing self-weight, improving fire resistance, enhancing durability, and reducing material consumption. These advantages result in cost

Design and Numerical Analysis of Gusset Plate Connections in Compression

ce/papers, Volume 8, Issue 6, Page 862-867, December 2025.
Abstract This paper investigates the compressive resistance of gusset plate connections, focusing on single‐sided bracing configurations with eccentric load. A total of twelve full‐scale tests were performed on CHS bracing members connected via gusset and cleat plates using bolted joints. The specimens varied in gusset plate thickness, steel grade, and

Nonlinear Finite Element Analysis of Tubular Steel Wind Turbine Towers near Man Door and Ventilation Openings to Optimize Design against Buckling

Vibration
The safe and cost-effective design of wind turbine towers is a critical and challenging aspect of the future development of the wind energy sector. This process should consider the continuous growth of towers in height and blades in length.

Application of the RRD Concept from Shell Buckling to Plate Buckling Problems

ce/papers, Volume 8, Issue 6, Page 1271-1276, December 2025.
Abstract EN 1993‐1‐5 rules the plate buckling proof of unstiffened and stiffened plated elements. Due to the complex load‐bearing behavior, different stability phenomena must be considered, like plate‐ and column‐like buckling, local buckling, torsional buckling of the stiffeners, patch‐loading, etc.
