Abstract

This chapter explores the rapidly evolving field related to incorporating information obtained through structural health monitoring (SHM) into the design, maintenance, and management of civil structures. Herein, the employment of monitoring technologies is investigated with respect to the following topics: development of a strategic, top-down monitoring approach; collecting the most critical information, at the right time, with the right instrument; probabilistic formulation of the analysis; conducting structural assessment; updating with monitoring information; life-cycle costing; and inclusion of risk. Simple examples are utilized to highlight the issues related to the use of monitoring technologies as a natural part of design and management. In this article, the need for performance-based design, several examples of monitoring-based structural assessment, and calculating life-cycle costs are treated in detail. In the end, the reader should gain an appreciation of recent progress in the rapidly developing field of SHM, some of the considerations for its implementation, and needs for further study.
