Structural Health Monitoring: research and practice
No full textStructural Health Monitoring is one of the preferred research topics in structural engineering but practical applications are still behind, at least in the civil sector. The paper is aimed at reviewing the main research achievements on the subject and to argue about the reasons because practical applications still encounter difficulties in becoming a standard practice in civil engineering. Structural health monitoring concepts and current design approaches are also discussed with consideration of the safety of monitored structures versus conventional non-monitored ones. Existing standards on structural monitoring and the need for the development of new standards integrating design, maintenance and management of constructed facilities are addressed
SHM of civil structures: expectations and perspectives
No full textIn the last years, SHM has been the subject of intensive developments also in civil engineer-ing. In practical applications, this has however resulted in complex instrumentation systems, difficult to be efficiently designed and expensive to be installed and maintained. Different approaches and a large variety of data interpretation tools have also been developed and applied. However, the issue of reliability of damage identification is still an open question. Due to the above situations, the use of SHM is still far from becoming a standard practice. The paper reviews the main achievements in the SHM discipline and the corresponding perspectives in view of practical applications. Research areas able to improve the effectiveness of SHM in the civil engineering field and to meet the expectations of potential users are addressed. The improvement in the reliability of monitored vs. conventional structures and its potential impact on design codes is also taken into account
Structural Health Monitoring Standards
No full textAlthough Structural Health Monitoring (SHM) techniques can be considered relatively mature, at least from the scientific point of view, they have not yet become a standard practice in civil engineering because of several reasons. One of these reasons has been individuated in the lack of comprehensive standards addressing the complete SHM process and especially potential utilization. The paper is aimed at briefly reviewing existing standards and tracing the lines for possible extensions, based on experiences gathered from the field and the actual evolution of SHM techniques. Lifecycle approaches including SHM are considered as well. In addition, the relationships between Structural Health Monitoring and Design Standards are addressed, raising the question whether in the design of a monitored structure and of a traditional one, the same safety coefficient should be applied. Consideration is given to the aspect of uncertainty modelling in both cases
Examples of Future Potential Smart Civil Structures
No full textThis paper is derived from an invited lecture given at the CIMTEC '08 International Conference. The paper starts reviewing the problems that the structural engineer of tomorrow will have to solve by taking advantage of the smart technologies. As a second aspect, the paper summarizes the smart technologies already available or that will most likely become available in the near future, in order to individuate the opportunities that these technologies will offer for the conception of innovative smart civil structures. Some examples of future smart civil structures that can be based on such technologies are finally presente
