Tie Beam

 

(in construction), a bar or rod, usually horizontal, that is under tension and connects the end joints of a building structure, which are subject to horizontal thrust forces. By tightening the ends of the structures, the tie beam absorbs the thrust, relieving the supports of the horizontal force. Tie beams may be made of metal or reinforced concrete (less frequently, wood); they are used in arches (arch trusses), vaults, bridge structures, and building roofs when a thrust-bearing support system is not suitable for economic or other reasons.

tie beam

1. On individual pile caps or spread footings which are eccentrically loaded, a beam (usually of reinforced concrete) used to distribute horizontal forces to other pile caps or footings; a strap, 2.
2. In roof framing, a horizontal timber connecting two opposite rafters at their lower ends to prevent them from spreading; also see collar beam.
