ABSTRACT

The successful design and implementation of the SHMS require a holistic oversight of the structural dynamic characteristics of the bridge, the possible damage conditions, instrumentation to capture possible damage scenarios, data management, signal processing techniques to transform sensed data into structural diagnostics and proper communication interface with authority for decision-making.

The aim of this work is to present a framework for SHMS design, acknowledging the need for interdisciplinary collaboration and definition of clear decision stages and later overview that allows interaction to achieve performance objectives. The framework makes distinctions regarding instrumentation and diagnostics in a SHMS. The framework is described as a process in which one has to evaluate a series of technical and decision aspects to achieve desired performance for the whole system configuration and specific objectives for instrumentations and diagnostics.

The paper follows the structure of the framework explaining the different blocks, relationships and motivations to include them within the framework. The numbers within the blocks in Figure 1 are related to the chapter where it is addressed in the paper. Finally the configuration of an implemented SHMS is analyzed based on the proposed framework as an application example.

We emphasize some of the underlying opportunities to meet desirable attributes for a SHMS. Some of these opportunities can be unfolded as research questions. There is much research still to be done regarding system optimal configuration, e.g. damage characterization effectiveness of a sensor system and a corresponding processing scheme is still and open question for multiple processing schemes and minimum sensor placement.
