Fire performance evaluation of GFRP-balsa sandwich bridge decks

Bridges are a critical component of national infrastructures and economies. A significant percentage of bridges built all around the world are made of reinforced concrete which according to building codes have a life span between 80-100 years. However, str ...

Bridge enhancement by means of the UHPFRC Technology: concepts and recent applications

Eugen Brühwiler

Existing bridges in reinforced concrete (RC) need to be enhanced in order to comply with utilization and safety requirements of future use, in particular for higher traffic loads. Such enhancements comprise strengthening to increase the structural resistan ...

Adding value to bridges by monitoring and UHPFRC technology

Eugen Brühwiler

Novel structural engineering methods and technologies are urgently needed to improve the performance of existing structures, such as bridges. Limited funding and ever increasing user demands challenge current technologies which are often invasive and not c ...

Fatigue safety verification of a steel railway bridge using short term monitoring data

Eugen Brühwiler, Bartlomiej Wojciech Sawicki, Mariia Nesterova

The case study of the fatigue safety examination of the 120 years old steel riveted bridge carrying a single railway track on two main girders is presented. The overall assessment according to the Swiss Standard SIA 269 for existing structures indicated su ...

Durability and fatigue performance of a typical cold-curing structural adhesive in bridge construction

Maria Savvilotidou

The science of adhesives and adhesion for structural connections has undergone significant development during the last few decades - and successfully so in a wide variety of industries. Recent applications of structural bonding are being adopted in the con ...

Large scale fiber bridging in mode I intralaminar fracture. An embedded cell approach

John Botsis, Georgios Pappas, Luis Pablo Canal Casado

Fiber reinforced composites can develop large scale bridging upon mode I fracture. This toughening mechanism depends on the constituents and the geometry of the specimen, and is especially important in unidirectional laminates when fracture is parallel to ...

Performance of Pedestrian-Load Models through Experimental Studies on Lightweight Aluminum Bridges

Scott Walbridge, Ann Christine Sychterz

Aluminum structures provide a high strength-to-weight ratio, are corrosion resistant, and are esthetically pleasing. Hence, their use in bridge construction has recently begun to increase, especially for pedestrian bridges. Because of their relative light ...

In situ X-ray Diffraction during Casting: Study of Hot Tearing in Al-Zn alloys

Jean-Marie Drezet, Güven Kurtuldu, Bastien Gilbert Pierre Mireux

During solidification of metallic alloys, coalescence corresponds to the formation of solid bridges between grains when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behaviour of solidif ...

Measurement of Mechanical Coherency Temperature and Solid Volume Fraction in Al-Zn Alloys Using In Situ X-ray Diffraction During Casting

Jean-Marie Drezet, Güven Kurtuldu, Bastien Gilbert Pierre Mireux

During solidification of metallic alloys, coalescence leads to the formation of solid bridges between grains or grain clusters when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behavior ...

Numerical study on the force-deformation behaviour of masonry spandrels with arches

Katrin Beyer, Sujith Mangalathu Sivasubramanian Pillai

This paper presents a numerical study on the force-deformation behaviour of masonry spandrels supported on arches which are analysed using simplified micro models. The model is validated against results from quasi-static cyclic tests on masonry spandrels. ...

Interaction between Bond and Deviation Forces in Spalling Failures of Arch-Shaped Members without Transverse Reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Sylvain Plumey

This paper investigates the structural behavior of reinforced concrete (RC) arch-shaped members without transverse reinforcement subjected to bending. Such members have typical applications in tunnels, cut-and-cover structures, shells, vaults, ducts, silos ...

Accurate fatigue stress determination in concrete railway bridges considering rail track - structure interaction

Eugen Brühwiler, Andrin Herwig

So-called “non-load bearing” parts of (railway) bridges increase the stiffness and decrease the stresses in short span bridge structures. The rail track, consisting of ballast, sleepers and rails, has a non-linear behaviour and its rigidity depends on the ...
