Precast Concrete Deck-to-Girder Connection using UHPC [PDF]

, 2019
The implementation of ultra-high-performance concrete (UHPC) in bridge construction has been growing rapidly in the last two decades due to its excellent mechanical properties, workability, and durability.

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

STRUCTURAL BEHAVIOR OF GFRP-CONCRETE COMPOSITE COLUMNS UNDER AXIAL LOAD

International Journal for Computational Civil and Structural Engineering
Glass Fiber Reinforced Polymer (GFRP) is emerging as an effective alternative to traditional steel in construction due to its superior ability to withstand high loads, light weight, corrosion resistance and low maintenance costs.

Anchorage System Contribution to Post‐Tensioned Bridge Collapse

Engineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Experimental Investigation on Flexural Behavior of Precast Segmental Ultra-High-Performance Concrete Box-Girder with External Tendons for Long-Span Highway Bridges

Buildings
A precast concrete segmental box-girder bridge (PCSBGB) is one of the most popular styles of Accelerated Bridge Construction (ABC). To address some common challenges (low durability, poor integrity, and construction inconvenience) in PCSBGBs, this paper ...

High performance WR-1.5 corrugated horn based on stacked rings

, 2014
We present the development and characterisation of a high frequency (500-750 GHz) corrugated horn based on stacked rings. A previous horn design, based on a Winston profile, has been adapted for the purpose of this manufacturing process without ...

Experimental and ANN Modeling of Mechanical Properties and Surface Quality in Multi‐Material FDM Printing: Effects of Retraction Parameters

Polymers for Advanced Technologies, Volume 37, Issue 5, May 2026.
ABSTRACT In fused deposition modeling (FDM), retraction related parameters are usually adjusted to reduce stringing and oozing; however, their combined effects on mechanical performance and surface quality, particularly in multi‐material printing, remain insufficiently quantified.
