Abstract
The paper presents a series of specific cases for the establishment of the neutral area and of the circular plates rigidity, with radial and welded ribs, having variable height. The inferred relations take into account the coefficients of admission, which characterize the orthotropical structures. The illustration praises the favorable effect of the ribs and of the welding seams, above the rigidity of the circular stiffed plates.
