شناسايي مدل اتصال سازه توسط نتايج آزمايش مودال

Dynamic behavior of a structure is significantly affected by the properties of its joints. This effect is more important in light weight structures with low damping such as airspace structures. In this paper two models for joint interface are presented and their properties are identified using modal testing results. In the identification procedure the characteristic equation of motion is used to obtain joint parameters. A good correlation between identified model and the modal testing results is obtained.
