Abstract:This paper is a state-of-the-art discussion on dynamic modeling theory and its application to scale modeling of reinforced concrete structures. Dimensional analysis is used to develop similitude requirements according to which the geometry, initial and boundary conditions, material properties and the loading of the model and prototype have to be related so that the behavior of the latter can be expressed as a function of the behavior of the former. The discussion focusses on various types of models that can be utilized to simulate the dynamic response of structures in the elastic and inelastic range. Commonly encountered problems in achieving satisfactory similitude are outlined and assessed as to the effect they may have on the reliability of prototype response prediction.
