Experimental and analytical investigation of shear-reinforced concrete and dowel action

Codes of practice can be overly conservative, particularly for the shear resistance of reinforced concrete beams with shear reinforcement when large loads act close to supports. This thesis addresses the topic by proposing a refined design approach based o ...

Exploring the potential of the critical shear crack theory for reinforced and post-tensioned glass beams: Initial analysis and experiments

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

In the evolution of structural glass beam elements, the requirements for post-fracture load bearing capacity and safe failure behaviour have led to the development of reinforced and post-tensioned beams. Maximum bending capacity in the post-fracture state ...

Environmental and Life-Cycle Cost Evaluation of a Composite Timber-UHPFRC Bridge

Eugen Brühwiler, Numa Joy Bertola

Ultra-High-Performance Fibre Reinforced Cementitious Composite (UHPFRC) has recently been used to design lightweight structures and strengthen existing ones, with more than 300 applications in Switzerland. Several composite timber-UHPFRC bridges have been ...

Fire performance evaluation of GFRP-balsa sandwich bridge decks

Niloufar Vahedi

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 ...

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 ...

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 ...

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 ...

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 ...

Influence of monitoring duration on measured traffic action effects on road bridges

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

This paper analyses the influence of monitoring duration on the obtained results using two long term (2.5 years) monitoring campaigns. Two road bridges with different nature of traffic are considered: (a) a heavily loaded two-lane highway viaduct and (b) a ...
