Title

Structural Health Monitoring in Civil Infrastructure Applications: New Perspectives

Abstract

This paper provides a critical review of current structural health monitoring (SHM) technologies for bridge management, proposes a hybrid computational/instrumented simulation framework of a large-scale bridge structure, introduces and characterizes a transformative concept of structural behavior monitoring (SBM), illustrates its attributes with examples, and discusses its potential impacts to ensure structural safety and durability of bridges. The hybrid framework can address both global and local behavior monitoring in an operation-related manner. Such a model can take into account the randomness of loads, materials, and environment. The substantial shift from the current SHM to the future SBM concept will generate a surge of new research interests that satisfy both the academic quest for scientific and technological explorations and the pragmatic needs for retrofit design and maintenance solutions in deteriorated bridges and other civil infrastructure such as water systems, dams, and levees. The proposed concept will change engineers' perception from the less favorable SHM to the receptive SBM strategy, thus having significant impact on technological challenges associated with the preservation of the U.S. bridge inventory.
