Abstract:
SP73 The small-scale dynamic model is a powerful tool for understanding structural behavior where analytical techniques are inadequate. Eleven papers are presented in this volume, beginning with similitude requirements and dynamic properties of model materials. Four papers are included on seismic loading of frame structures, frame-wall structures, arch dams, and long-span bridges. Other topics include air-blast loading of buried structures; impact loadings on beam-to-column joints and on reinforced concrete slabs; and vibration studies of both floor slabs and large panel buildings.

An experimental and finite element analysis of the impact of a stel rod on a reinforced concrete slabl has been conduted. The object was to study the correlation between experimental and theoretical results. It was found that detailed information of nonlinear wave propagationm concrete crushing and cracking, and yielding of reinforcment steel could be obtained from the finite elem,ent analysis. A good coorelation between experimental and theoretical results was achieved. The development of different failure mechanisms can clearly be followed in the theoretical results. Such information should be very valuable in connection with the formulation of simple design formulas.

Small size models of two concrete floor systems have been tested for their elastic and post-elastic behavior under in-plane shear action. Parameters studied include cyclic and monotonic loading, shear span aspect ratio, effect of gravity load and repair by epoxy injection method. This report describes the development of the model and techniques used in the testing. Preliminary test results and conclusions are also presented.

This paper presents a methodology for designing, fabricating, and testing small-scale dynamic models of precast concrete shearwalls originating in the construction of large panel precast concrete buildings. Design and construction of a set of 3/32-scale models which satisfy dynamic similitude is presented. Resonent vibration testing of three-story and five-story precast concrete shearwall models on a small shake table is described. Additional monotonic and cyclic tests on six five-story shearwall models under simulated earthquake loading are presented. The main parameters in these tests were the amount of steel in the vertical ties and cyclic versus monotonic loading.

Helmut Krawinkler and Piotr D. Moncarz
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.
