Automatic Degradation Detection During a Dynamic Loaded Beam Test

The remaining service life of concrete structures strongly depends on the corrosion level of the reinforcement bars. It explains that measuring the corrosion rate is a key issue in monitoring the structural health of concrete structures. A common and appropriate technique used to evaluate the instantaneous corrosion rate of steel reinforcement...

Structural monitoring and modal properties of a real time bridge and lab tests

For understanding the actual state of durability of concrete structures, it is important to know its response due to external loading. This response mainly depends on the actual structural and material properties of the structure, while loaded. Mechanical and chemical degradation are the main mechanisms that may affect these properties with time...

Modal analysis of a concrete highway bridge: Structural calculations and vibration-based results

In the field of civil infrastructure, Structural Health Monitoring systems are implemented more and more frequently with the aim to safeguard the safety and service-life of structures such as bridges and tunnels. Changes in the integrity of the material and/or structural properties of this class of structures is known to adversely affect their...

Data-intensive structural health monitoring in the infrawatch project

The InfraWatch project is a Dutch research project, aimed at developing novel techniques for large-scale monitoring of concrete infra-structures. The project involves a large bridge, fitted with multiple types of sensors that capture the high-resolution dynamic behavior of the bridge. With 145 sensors measuring at 100 Hz, a huge amount of data...
