Comparison With Other Vault Designs
The construction of a groin vault can be understood most simply by visualising two barrel vault sections at right angles merging to form a squarish unit. The resulting four ribs convey the stress loading to the four corners, or piers. The more complex groin vault is intrinsically a stronger design compared to the barrel vault, since the barrel vault structure must rest on long walls creating less stable lateral stress, whereas the groin vault design can direct stresses almost purely vertically on the piers. A common association of vaulting in cathedrals of the Middle Ages involves a nave of barrel vault design with transepts of groined vaulting. Rib vaults resemble groin vaults but introduce structural ribs running along the angles which carry much of the weight, making possible much greater variations of proportion.

Famous quotes containing the words comparison with, comparison, vault and/or designs:
“[Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?”
—Sarah M. Grimke (1792–1873)
“What is man in nature? A nothing in comparison with the infinite, an all in comparison with the nothing—a mean between nothing and everything.”
—Blaise Pascal (1623–1662)
“Heaven froze above, severe; the clouds congeal,
And through the crystal vault appeared the standing hail.”
—Geoffrey Chaucer (1340?–1400)
“It is a mighty error to suppose that none but violent and strong passions, such as love and ambition, are able to vanquish the rest. Even idleness, as feeble and languishing as it is, sometimes reigns over them; it usurps the throne and sits paramount over all the designs and actions of our lives, and imperceptibly wastes and destroys all our passions and all our virtues.”
—François, Duc De La Rochefoucauld (1613–1680)
