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...

This chapter discusses aspects that should be considered prior to every load test. The first questions that needs to be answered are “Is this bridge suitable for load testing?” and “If so, what are the goals of the load test?” To answer these questions, information must be gathered and preliminary calculations should be carried out. In order to...

This chapter reviews the existing codes and guidelines for load testing of structures. A summary of the main requirements of each existing code is provided, with a focus on the determination of the required load and measurements. The requirements for load testing of bridges and buildings are revised, for new and existing structures. An...

This chapter discusses the aspects related to the preparation of load tests, regardless of the chosen type of load test. After determination of the test objectives, the first step should be a technical inspection of the bridge and bridge site. With this information, the preparatory calculations (assessment for existing bridges and expected...

This chapter discusses the aspects related to processing the results of a load test after the test. The way in which the data are processed depends on the goals of the test. As such, the report that summarizes the preparation, execution, and post-processing of the load test should clearly state the goal of the load test, how the test addressed...

This chapter discusses the aspects related to the execution of load tests regardless of the chosen type of load test. The main elements required for the execution of the load test are the equipment for applying the load and the equipment for measuring and displaying (if required) the structural responses. This chapter reviews the commonly used...

This chapter reviews concepts related to the uncertainties associated with structures and how the results of load tests can be used to reduce these uncertainties. When an existing bridge is subjected to a load test, it is known that the capacity of the cross section is at least equal to the largest load effect that was successfully resisted. As...
