Request a sales quoteThe Life of Structures: Physical Testing covers the proceedings of a seminar of the same name. The said seminar is focused on the actions on structures and the performance of existing populations of structures; the properties and performance of building materials; and the internal and external environments of buildings. The book covers topics such as the methodology for the prediction of the life of existing structures; reliability of service-proven structural systems; and some effects of micro-environment on materials. Also covered are subjects such as the assessment of structures through field measured dynamic response; physical properties of structures investigated by dynamic methods; and the stiffness damage test. The text is recommended for engineers who would like to know more about the strength and lifespan of structures, as well as the effectivity of the materials involved in their construction.
