Reliability analysis of welded stud shear connectors on simply-supported bridge girders

Scott Walbridge, Matthew James Sjaarda

This paper examines the reliability of welded stud shear connectors for steel-concrete composite bridge girders. A finite element model of a simply-supported bridge was created featuring link connector elements representing the shear studs between beam and ...

Study on Mechanical Performance of Prestressed UHPFRC U-Beam Bridges

Eugen Brühwiler

The forms of U-shaped UHPFRC beams have not been investigated for the highway footbridge. Compared with the traditional section forms, the U-shaped UHPFRC beams can reduce the material consumption under the condition of providing the same bearing capacity. ...

Assessment of the Environmental Impacts of Bridge Designs Involving UHPFRC

Eugen Brühwiler, Célia Marine Küpfer, Numa Joy Bertola

Ultra-High-Performance Fibre-Reinforced Cementitious Composite (UHPFRC) has been developed to design lightweight structures and enhance existing designs. As the environmental footprint of the construction industry must be significantly reduced, the potenti ...

FATIGUE EXAMINATION OF REINFORCED-CONCRETE BRIDGE SLABS USING ACOUSTIC EMISSION AND STRAIN MONITORING DATA

Imane Bayane

The examination of bridges under service loading is key for understanding their condition and thus for their sustainable and efficient use. The need to extend the service duration of existing bridges is increasing, and therefore, efficient tools for examin ...

Enhancement of riveted steel bridges by adding a trough in UHPFRC acting in composite action

Eugen Brühwiler

Riveted railway bridges are commonly considered as being “old”, having fatigue damage and are therefore replaced. While this practice should be by now obsolete by using novel engineering methods like structural monitoring, prolongation of the service durat ...

European traffic on road bridges and recalibration of lambda factor for fatigue verification

Gianluca Bianchi

The evolution of European traffic, combined with the current works of revision of the Eurocode (CEN250 project 2nd Eurocode generation), represents an opportunity to improve the simplified method for fatigue checks (also known as the lambda method) for roa ...

Strengthening of steel beams using iron-based shape memory alloy (Fe-SMA) strips

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori, Julien Michels

The current study presents a retrofit system, which can be used for strengthening of steel bridge beams using (un-bonded) mechanically-anchored iron-based shape memory alloy (Fe-SMA, ‘memory-steel’) strips. After anchoring, the Fe-SMA strips are activated ...

Flat prestressed unbonded retrofit system for strengthening of existing metallic I-Girders

Alain Nussbaumer, Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In this study, a novel retrofitting system is developed to strengthen existing metallic I-girders using prestressed unbonded carbon fiber reinforced polymer (CFRP) plates. The system relies on a pair of mechanical clamps. Each clamp holds two CFRP plates ( ...

Fatigue Study of the Linthkanal-Brücke

As fatigue cracks were discovered under the bridge deck of the 48 years old railway bridge Linthkanal-Brücke, located near the Ziegelbrücke town in Switzerland, a few studies were conducted to understand the mechanism behind the cracks formation. However, ...
