Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes

open access: yesStructural Concrete, EarlyView.
Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...

Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

open access: yesStructural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

open access: yesStructural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Contribution of dowel action to interfacial shear transfer in flat joints with unbonded posttensioned bars for precast segmental bridges

open access: yesStructural Concrete, EarlyView.
Abstract Dry joints are widely used in precast segmental bridge construction because they simplify assembly and accelerate erection. Incorporating fasteners crossing flat dry joints represents an innovative configuration for this type of connection.

Alignment of Agile and Modular Open Systems Approach (MOSA) Principles in Systems Engineering

open access: yesSystems Engineering, EarlyView.
ABSTRACT Organizations have consistently sought faster and more efficient methods for producing and delivering products. Agile principles offer essential guidance for shaping their policies and practices. The Agile Manifesto (AM) outlines 12 core principles for guiding software development but can also be applied in other contexts.
