In this paper, large deformations and bending behavior of circular steel plates with clamped edges and variable thickness are experimentally investigated under the effect of uniform lateral loading. For the purpose of this experimental program, some steel circular plates are prepared and stiffened by attaching smaller full circular or an annular plate at the centre. Then the models are instrumented and placed in the test machine in such a way that a clamped condition is provided at the edge. The test measurements are performed using attached strain gages and displacement transducers which are installed on all specimens and connected to computer through a data logger. For uniform lateral loading, a vacuum pump is employed. The measured data is processed and presented in the form of tables and graphs to discuss the bending behavior of stiffened circular plates. Then the obtained results are evaluated by nonlinear analysis of the tested models using finite element solution. In this analysis the material and geometric effects, as well as the geometric imperfections are included. A very good agreement is found between both experimental and numerical studies.
