Long-term material and structural behavior of high-strength concrete cantilever bridge: Results of 20 years monitoring

In 1997, the Second Stichtse Bridge was built in the Netherlands using the balanced cantilever method. The use of high-strength concrete was proposed. At that time, the long-term behaviour of this material was not known, and no code provisions were applicable. Therefore, it was proposed to monitor the material behaviour and the deflections of...

Full-size field test of prestressed concrete T-beam bridge

In the Netherlands, approximately 150 prestressed T-beam bridges with cast-in-between decks and mainly built in the sixties are still in service. Upon assessment, the prestressed beams often do not fulfil the design codes requirements, whereas upon inspection, they show no signs of distress. For the assessment, additional load transfer...
