ABSTRACT
ABSTRACT: A general solution for the dynamic analysis of plates stiffened by arbitrarily placed parallel beams with deformable connection is presented. According to the proposed model, the stiffening beams are isolated from the plate by sections in the lower outer surface of the plate, taking into account the arising tractions in all directions at the fictitious interfaces. These tractions are integrated with respect to each half of the interface width resulting two interface lines. Their unknown distribution is established by applying continuity conditions in all directions taking into account their relation with the interface slip through the shear connector stiffness. Any distribution of connectors in each direction can be handled. The proposed model permits the evaluation of the shear forces at the interfaces in both directions. Three additional finite element models using beam, shell or solid finite elements are also employed for the verification of the accuracy of the results.
