Condition-Based Inspection Models of Major Civil-Engineering Structures

A method of modelling the task of inspecting major civil-engineering structures is proposed. The objective is to relate measures of both the integrity of the structure and its maintenance cost to the inspection frequency. The option exists within the model to adopt a variety of physical testing techniques. Delay-time analysis is utilized, and the behaviour of the model illustrated with a numerical example. Some possible developments of the model and extension are discussed along with current input requirements.
