In some cases, such as new building bridges, the regulations require to perform "load tests, both static and dynamic, to evaluate the structural behavior prior to implementation. In other cases the lack of information and inability to perform a numerical analysis, force load tests compel to raise a "semi-break", to assess the residual bearing capacity of a structural element.
Moreover, often there is a need to monitor the assessment of some variables, using specific tools with equipments to catch automated data,through "data-loggers, or directly by computers.
Among other things, load testing and instrumentation most commonly carried out by our Department, are as follows:
- Load testing of structural elements to "break" in the laboratory.
- Load tests on pedestrian bridges, road and rail, with static and dynamic measurements.
- Load tests to "semi-break" for evaluation of residual bearing capacity of difficult items with damage assessment (corrosion, accidents by fire or explosion, chemical attack), or use changes and lack of reliable information from the project.
- Measurement of crack width evolution of injury due to structural stability problems, or seats of foundations.
- Measure movements of nearby buildings during excavation and containment.
- Verification of structural behavior and foundations during the first filling and emptying containers of water.
