Health Assessment of Engineered Structures : Bridges, Buildings and Other Infrastructures.

Health Assessment of Engineered Structures : Bridges, Buildings and Other Infrastructures.

Health Assessment of Engineered Structures has become one of the most active research areas and has attracted multi-disciplinary interest. Since available financial recourses are very limited, extending the lifespan of existing bridges, buildings and other infrastructures has become a major challeng...
