A Method Of Health Diagnosis Of Bridges Based On Load Response Effects

A bridge's health state involves many factors such as bridge's structure form, material adopted, rationality of design, quality of construction and action of load etc. Its health state mainly depends on action extent and action process of various loads. Different bridges show diverse response features to load action. So it is feasible to take preliminary diagnosis on the bridge's health state according to the bridge's response features to load action. According to a vast amount of on-the-spot monitoring data of bridges, the diagnosis method of the bridge's health state based on load response effect is put forward. An example has been given.
