Structure Dynamic Theories for Damage Diagnosis
Abstract
The present research aims toward developing structural theories which can be used to diagnose the fracture damage of structures and to assess the reliability of the damaged structures. Such theories, once verified experimentally, will be available for design engineers to apply to the damageable structures. It can also be the base for methodology which analytical and testing engineers can develop to diagnose and assess the reliability of the existing structures. It is assumed that the structures under consideration may develop damage through extreme excitations. Such damage can be defined as cracks occurred in the structures, the amount of energy dissipation, the deformation or any combination of the three. Therefore, it is important to know when damage has occurred in a structure. When it has, it is desirable to be able to locate it and estimate its extent. Following the damage diagnosis, the principal components for damage are 1) to develop theories for the reliability assessment of damageable structures and estimate the damage in a structure, and (2) to develop and improve mathematical models which simulate the behavior of damageable structures. These assessment theories will assist the engineers to achieve a specified predictive accuracy in design, and to obtain a more realistic assessment of the existing damageable structures.
