Following introductory reference to the load-carrying system of multibeam bridges (theory of orthotropic plates) the paper reports findings of test series on a large-scale model bridge of prestressed concrete. It is shown that such a bridge can accurately be analyzed as an orthotropic plate. The influence of factors which affect the behavior of the structure-slip between adjacent beams, interaction of shear keys, degree and location of lateral post-tensioning, etc.-have been studied. Empirical formulas for the relationship of the stiffness properties are derived.
