TL;DR: In this article, the problem of free vibration and buckling of isotropic clamped rectangular plates of variable thickness is investigated by using Galerkin's variational method, where the thickness of the plate varies linearly along the x axis and this variation is taken to be symmetric with respect to the middle surface.

TL;DR: In this paper, a modified approach based on the orthotropic plate theory for computing the natural frequencies of bridge slabs is presented through a set of empirical relationships between the plate parameters, and the results from the present investigation are compared with those obtained by other methods; good agreements are obtained.

TL;DR: In this paper, the suitability of the Galerkin variational method for solution of problems of buckling under the action of in-plane forces and of free vibration of skew plates is studied.

TL;DR: In this paper, a finite element displacement model is presented for the dynamic and static analysis of clamped and simply supported skew sandwich plates, and the geometric admissibility conditions of the principle of minimum total potential energy are satisfied by representing the assumed displacement pattern by a polynomial function.

TL;DR: In this article, a forced vibration analysis of longitudinally stiffened, simply supported orthotropic bridge decks utilizing a new concept of interconnected beam idealization is presented. But this analysis cannot be successfully utilized in the case of short span bridges where plate action is predominant and where the determination of the distribution of dynamic deflections and amplification factors at critical sections of such plates is of prime concern.
