Truss—A number of timbers framed together to bridge a space, designed to be self-supporting and to carry other timbers. The trusses of a roof are generally named after a peculiar feature in their construction, such as King-post, Queen-post, Hammer-beam, Cruck; see Roofs.

Tufa (Calcareous)—Spongy deposit formed by the action of water on limestone and resembling volcanic lava; often used in vaulting on account of its light weight.

Tympanum—The triangular or segmental field in the face of a pediment or in the head of an arch.

Vaulting—An arched ceiling or roof of stone or brick, sometimes imitated in wood and plaster. Barrel Vaulting is a continuous vault unbroken in its length by cross-vaults. A Groined Vault (or Cross-vaulting) results from the intersection of simple vaulting surfaces. A Ribbed Vault is a framework of arched ribs carrying the cells that cover in the spaces between them. One bay of vaulting, divided into four quarters or compartments, is termed quadripartite; but often the bay is divided longitudinally into two subsidiary bays, and the vaulting bay is thus divided into six compartments and is termed sexpartite. Increased elaboration is given by tiercerons, secondary ribs springing from the wall-supports and rising to a point other than the centre, and liernes, tertiary ribs that do not spring from the wall-supports, but cross from main rib to main rib. In fan-vaulting numerous ribs rise from the springing in equal curves, diverging equally in all directions, giving fan-like effects when seen from below.

Venetian Window—Similar to Palladian window.

Vesica Piscis—An oval frame, pointed at top and bottom, common in mediaeval art.
