Evolution of a Bridge Damage-Detection Algorithm

Abstract

Several of the steps, iterations, and refinements required to develop one of the many pieces of the structural health monitoring (SHM) system puzzle are described. These steps include devising initial concepts, alpha testing, analytical investigation, beta testing, concept upgrades, and field evaluations. Although not necessarily a blueprint for the development of such systems, the report serves as a case study for taking an initial concept through multiple steps that culminate in a validated approach. As SHM becomes a more widely adopted and accepted bridge evaluation protocol, it will be imperative that developers understand the steps required to develop such systems. The work presented is one example of such a process.
