  BUTTRESS. The Columbia Encyclopedia: Sixth Edition. 2000   (Site not responding. Last check: 2007-10-12)
The Romans employed buttresses, which sometimes projected from the exteriors of the walls and were then left as mere piles of masonry, without architectural treatment.
But in the large structures, such as basilicas and baths, the buttresses that received the thrusts from the main vaulting were confined to the interior of the building, where they served also as partition walls.
They devised the flying buttress, an arch of masonry abutting against the wall of the nave; the thrust of the nave vault could thus be received and transferred to the vertical buttress built against the outside walls of the side aisles.

 Buttress - LoveToKnow 1911
The buttresses of the early Romanesque churches were only pilaster strips employed to break up the wall surface and decorate the exterior.
The introduction of ribbed vaulting, extended to the nave in the 12th century, and the concentration of thrusts on definite points of the structure, rendered the buttress an absolute necessity, and from the first this would seem to have been recognized, and the architectural treatment already given to the Romanesque buttress received a remarkable development.
The buttresses of the early English period have considerable projection with two or three sets-off sloped at an acute angle dividing the stages and crowned by triangular heads; and slender columns ("buttress shafts") are used at the angle.

Buttressing suture/staple lines in thoracic surgery has been shown to promote healing and prevent breakdown, especially in situations where the native tissues have been compromised.
A pericardial fat pad flap is indicated for buttressing the bronchial suture/staple lines in various instances where chance of suture line failure may be increased by preoperative variables.
For larger buttressing needs only, the superior pericardial branches are preserved allowing the entire bulk of the pericardial fat pad to be used.

 Flying buttress - LoveToKnow 1911
FLYING BUTTRESS, in architecture, the term given to a structural feature employed to transmit the thrust of a vault across an intervening space, such as an aisle, chapel or cloister, to a buttress built outside the latter.
Though employed by the Romans and in early Romanesque work, it was generally masked by other constructions or hidden under a roof, but in the 12th century it was recognized as rational construction and emphasized by the decorative accentuation of its features, as in the cathedrals of Chartres, Le Mans, Paris, Beauvais, Reims, andc.
As a vertical buttress, placed at a distance, possesses greater power of resistance to thrust than if attached to the wall carrying the vault, vertical buttresses as at Lincoln and Westminster Abbey were built outside the chapterhouse to receive the thrust.

 Flying buttress - Wikipedia, the free encyclopedia
In architecture, a flying buttress, or arc-boutant, is a butt, usually on a religious building, used to transmit the thrust of a vault across an intervening space (which might be an aisle, chapel or cloister), to a buttress outside the building.
The employment of the flying buttress means that the load bearing walls can contain cut-outs, such as for large windows, that would otherwise seriously weaken the vault walls.
As a vertical buttress, placed at a distance, possesses greater power of resistance to thrust than if attached to the wall carrying the vault, vertical buttresses as at Lincoln Cathedral and Westminster Abbey were built outside the chapterhouse to receive the thrust.

We assessed the importance of tree buttresses as a microhabitat for the leaf litter
Both abundance and species richness of the herpetofauna were much greater in plots containing buttressed trees; higher species richness in buttress plots was attributed solely to greater abundance in these plots.
Buttress and non-buttress plots contained a similar species composition, and we found evidence of specialization on tree buttresses by a single species, the scincid lizard Sphenomorphus cherriei.

 East Buttress of El Cap
This is the beautiful, sweeping buttress at the far right end of the escarpment of El Cap.It should take about 45 minutes to reach the rope up spot which is 1000 feet above the valley floor and just short of a dropoff.

The East Buttress was first climbed in 1953 by two of the great composers of climbs, Allen Steck and Willi Unsoeld.
