000021495 520__ $$2eng$$aEffective thickness approaches are useful tools for a response prediction and the design of sandwich structures. In this contribution, we study their applicability to free vibration analysis of laminated glass beams – sandwich structures composed of glass layers connected with one or multiple compliant foils. These interlayers are made of polymer materials with frequency/temperature-dependent behavior. Here, the dynamic effective thickness approach, the modal strain energy method, and the Newton-type algorithm are applied to the complex eigenvalue problem for a three-layered laminated glass beam. The results of the modal analyses, in terms of natural frequencies and loss factors, are compared for all approaches. It is shown that the errors of the two simplified methods depend on the ambient temperature and the applied boundary conditions and that these errors can be large, especially for the loss factor.
