Example of Proof Load Testing from Europe

This chapter describes the proof load testing of viaduct Zijlweg at a position that is critical for bending moment and at a position that is critical for shear. The viaduct Zijlweg has cracking caused by alkali-silica reaction, and the effect of material degradation on the capacity is uncertain. Therefore, the assessment of this viaduct was...

Towards standardisation of proof load testing: pilot test on viaduct Zijlweg

Proof load tests of bridges can be very useful for structures with a lack of information, or for structures of which the effect of material degradation is difficult to assess. Contrary to diagnostic load testing, proof load testing is not well-defined in current standards in terms of required load and analysis of measurements. The risk...

Proof load testing of the viaduct De Beek

Proof load testing can be a suitable method to show that a bridge can carry the required loads from the code without distress. This paper addresses the preparation, execution, and analysis of a proof load test on a four-span reinforced concrete solid slab bridge, viaduct de Beek. The bridge has one lane in each direction, but was restricted to a...

Pilot Proof-Load Test on Viaduct De Beek: Case Study

For existing bridges, proof-load testing can be a suitable assessment method. This paper addresses the evaluation of a posted reinforced concrete slab bridge over a highway through proof-load testing, detailing the preparation, execution, and analysis of the test. As the target proof-load and the required measurements for proof-load testing...

Measurement Report on the Transition between Flexural and Shear Failure on RC Beams without Shear Reinforcement

This is a measurement report of the test series on reinforced concrete beams without shear reinforced carried out in Delft University of Technology from April 08, 2015 till July 01, 2016. The target of the research is to investigate the transition of shear failure and bending failure. In this report, the detailed information of the experimental...

Defining loading criteria for proof loading of existing reinforced concrete bridges

As the bridge stock in The Netherlands and Europe is ageing, various methods to analyse existing bridges are bemg studied. Proof loading of bridges is an option to study the capacity when crucial information about the structure is lacking. This information could be related to the material (for example, the effect of alkali-silica reaction on the...

Gravity Base Foundations for Offshore Wind Turbines

The scope of this study is to investigate the possibilities for applying Gravity Base Foundations at larger water depths. To do so the influence of various parameters for the foundation and turbine are investigated as well as the properties of the sub soil. It is concluded that it is technically possible to construct concrete Gravity Base...
