On the picture of the urchin-shell, the ribs are clear to recognize. The similarities between both construction-manners emerge in the spatial association of ribs, through what a peel-construction originates (although there are the single-ribs of the speed skating-hall in Erfurt from arched two-joint-borders) with both constructions in the third dimension. The difference consists that the rib-amplifications of the urchin-shell one by virtue of - and trains form-conclusive system with the peel-mantle. At the speed skating-hall however, the construction is even further dissolved, and the peel-mantle is not form-conclusive interconnected with the ribs. The by virtue of-conclusive system only is generally produced, as expresses cargos of the mantle into the Tragwerk is referred, however, Zwängungsspannungen (they can appear at the urchin-shell in the theory, because of which should have low dimension of her/its/their construction a petty influx, however, on the total-shell) avoids otherwis
