Graphite/epoxy composite adapters for the Space Shuttle/Centaur vehicle [PDF]

The decision to launch various NASA satellite and Air Force spacecraft from the Space Shuttle created the need for a high-energy upper stage capable of being deployed from the cargo bay.

Stability and plasticity interaction in building‐size steel sway frames

Steel Construction, EarlyView.
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.

Compression capacity of closely spaced double‐angle beam‐columns – Impact of joint stiffness

Steel Construction, EarlyView.
Abstract Usually, pinned ends are assumed to calculate the compression capacity of closely spaced double‐angle members. In reality, the joints used in practice provide additional rotational restraint at the member's ends, which significantly influence the compression member capacity of such built‐up sections.

The Pier Luigi Nervi's concrete structure of Palazzetto dello Sport: Modeling and dynamic characterization

Structural Concrete, EarlyView.
Abstract This paper presents a numerical and experimental study aimed at the modeling and dynamic characterization of the reinforced concrete structure of the Palazzetto dello Sport in Rome, designed and by Pier Luigi Nervi with Annibale Vitellozzi, and built by Nervi & Bartoli contractors in 1956‐57.

Robustness assessment of reinforced concrete structures for different failure scenarios

Structural Concrete, EarlyView.
Abstract This study describes the robustness assessment of 3D reinforced concrete structures analyzing the response of the 2D frames in different design configurations and failure scenarios. The structures are characterized by both frames with wide beams and seismic‐resistant frames with deep beams.

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...
