Continually increasing demands on infrastructures mean that maintenance and renewal require timely, appropriate action that maximizes benefits while minimizing cost. To be as well informed as possible, decision-makers must have an optimal understanding of an infrastructure's condition-what it is now, and what it is expected to be in the future. Written by two highly respected engineers, the first volume, Infrastructure Health in Civil Engineering: Theory and Components, integrates the decision making concept into theoretical and practical issues. It includes:An overview of the infrastructure health in civil engineering (IHCE) and associated theories In-depth description of the four components of SHCE: measurements, structural identification, damage identification, and decision makingDiscussion of how IHCE and asset management are appliedAn exploration of infrastructure health managementBuilt to correspond to the ideas presented in its companion volume, Applications and Management, this is an invaluable guide to optimized, cost-saving methods that will help readers meet safety specifications for new projects, as well as aging infrastructures at high risk for failure.
