Static and Fatigue Biaxial Flexural Behavior of Strain-Hardening UHPFRC Thin Slab Elements

Xiujiang Shen

Cast-in-place thin layers of Ultra-High Performance Fiber Reinforced Cementitious Composites (UHPFRC) on the specific zones of existing reinforced concrete (RC) bridge decks has been demonstrated to be a technically efficient and economic rehabilitation an ...

Fatigue Damage Factor Calibration for Long-Span Cable-Stayed Bridge Decks

Alain Nussbaumer, José Joaquim Costa Branco de Oliveira Pedro, Cláudio Alexandre Pereira Baptista

Part 2 of the Eurocode 3 (EN 1993-2) proposes a straight forward fatigue verification method using a single heavy vehicle model (FLM3) and a damage equivalent factor, lambda, to represent the fatigue damaging effects of the real traffic on road bridges. Th ...

Monitoring of the UHPFRC strengthened Chillon viaduct under environmental and operational variability

Eugen Brühwiler

Constructed in 1969, the Chillon viaducts constitute a vital component of the Swiss roadway network. The bridge deck was strengthened in 2015 by means of an Ultra High Performance Fiber Reinforced Cement-based Composite for alleviating the effects of deter ...

In response to ‘Six critical questions about smart spezialisation’

Dominique Foray

This paper has been written as a response to « Six critical questions about smart specialization » by R. Hassink and H. Gong. The paper starts with a reminder of what has not changed in terms of the basic principles and raison d’être of smart specializatio ...

“Pocket-Monitoring” for the fatigue safety verification of bridge members in steel and reinforced concrete

Eugen Brühwiler

The fatigue safety of the reinforced concrete deck slab of a sixty-year-old steel-concrete road viaduct as well as the riveted steel girders of a 130 year old railway bridge was questioned based on the results of conventional assessment consisting in "re-c ...

CHARACTERIZATION OF TENSILE BEHAVIOR IN UHPFRC THIN SLAB USING NDT METHOD AND DIC SYSTEM

Eugen Brühwiler, Xiujiang Shen

Proper test and analysis methods are necessary for characterizing the tensile behavior of strain hardening Ultra High Performance Fiber Reinforced Cementitious Composites (UHPFRC) accurately and representatively. In this paper, the direct tensile tests (DT ...

Rotational stiffness of web-flange junctions of pultruded GFRP decks

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The rotational behavior of the web-flange junctions (WFJs) of a pultruded glass fiber-reinforced polymer (GFRP) bridge deck system with trapezoidal cell cross-sectional geometry was investigated. The rotational response of three WFJ types, in two bending m ...

Deriving a load model for the braking force on road bridges: Comparison between a deterministic and a probabilistic approach

Katrin Beyer, André-Gilles Dumont, Marc-Antoine Fénart, Glauco Feltrin

The current provisions for the braking force in the Eurocodes are much more demanding than previously enforced national codes from most European countries. Hence, safety assessments of existing bridges may show a lack of compliance with the new safety requ ...

Multiaxial and variable amplitude fatigue in steel bridges

Cláudio Alexandre Pereira Baptista

Modern bridge construction all over Europe in the last decades, has highlighted the importance of steel solutions for the design of bridges. Steel bridges have become slender and lighter with the generalisation of welded connections. These features increas ...

Mitigation of Wind-Induced Vibrations in Long-Span Bridges using a Distributed Flap System

Klara Maria Boberg

Since the collapse of the Tacoma Narrows Bridge more than 70 years ago suppressing wind-induced instabilities has been a key aspect of the design of long-span bridges. The intensive experimental and theoretical research in wind engineering allowed research ...
