Investigation of the usage of SHCC as a closure pour to reduce the construction time of widening a prestressed concrete bridge

The Netherlands is currently facing a significant challenge regarding its highway system due to the rise in traffic, especially in densely populated areas like The Randstad. However, constructing new infrastructure or replacing old bridges is not a practical solution due to environmental concerns. Most of the country's prestressed concrete...

Modelling the interface in concrete-to-concrete connections between precast girders and cast-in-situ top layers

A significant part of composite concrete viaducts was built in the 50s and 60s. This has led to an increasing need for the reassessment of the precast concrete beam bridges in the Netherlands. Many of those bridges are nowadays subjected to higher traffic loads and consequently, have a certain risk of not complying with the currently used design...

Transverse load-spread of a voided bridge deck: Comparison between a grillage model and an orthotropic plate model

Orthotropic bridges can be modelled using a grillage model and an orthotropic plate model. The grillage model has some benefits (i.e.: shorter calculation time and easier to apply pre-stressing) compared to the orthotropic plate model. However, during the Blankenburgverbinding project Ballast Nedam experienced that the transverse load-spread of...
