LIA Inspections and Monitoring of Structures in Civil Engineering Works

To ensure the safety of structures and to improve the sustainability of large structures to avoid sudden collapses need continuous inspections and monitoring of structures of civil works.

The main purpose of monitoring civil structures is to support regular visual examinations or inspections based on non-destructive testing techniques.

Continuous structural health monitoring should provide data from the inside of a structure to better understand its structural performance and to predict its durability and remaining life time.

One example of an application are railway bridges that are more and more confronted with higher axle loads and higher train speeds as probably expected during construction. Another example are structures exceeding the designated life time.

The inspection of building structures and especially of bridges is mainly done visually nowadays. Therefore, the condition of the structure is examined from the surface and the interpretation and assessment is based on the level of experience of the engineers. An approach to continuous structural health monitoring techniques based on wireless sensor networks were presented, which provide data from the inside of a structure to better understand its structural performance and to predict its durability and remaining life time.
