Structure in the field or laboratory experiments with main purpose is to understand the given conditions of the actual behavior of innate characteristics or structure. Test results for various applications will also be one of the main goals. Work, which carries out a variety of structural analysis, based on the model obtained through experiments, often is referred to as structural re-analysis to obtain more exact behavior of the structure which is defined as a re-analysis of the structure. In a broader meaning, the structure analysis is used to accurately and then the resulting structure according to the load conditions is based on a load condition, or structural features of its own structure of the behavior of the observed behavior. Structure or structural features as modifying the behavior of innate value of about realistic system identification, as well as the structure of experimental methods have structural reanalysis also as structural dynamics modification.
