The tremendous advances in sensor technologies and data transmission have provided unique and timely opportunities for the structural health monitoring (SHM) of civil infrastructure. For SHM to be truly effective, the system must not just collect data regarding the response of infrastructure components, but must also be able to use this data to allow for rapid assessment of the health of the structure and even of the need and timeliness of maintenance and/or repairs. The SHM system must, therefore, intrinsically allow engineers to review the “health” of a structure within a network of such structures from a remote location and to reach decisions regarding its state using on-line tools working almost autonomously, thereby enabling a true 24/7 monitoring of response. Web-based monitoring enables this advancement. This article provides the rationale for the structure of and an example of a web-based SHM system.
