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.

The support was reinforced with two rows of V25-type steel tie beams anchored to the roof by means of strand bolts with the total length of 4.
The analysis indicated that the application of anchored tie beams caused the roof to initially move towards the working while later it was subject to compression.
c] of roof > 60 MPa), the applied reinforcement of steel yielding support by means of two tie beams anchored with strand flexible bolts can provide suitable working stability.
The new columns and tie beams comprise a complete, new, concrete structural support system for the building that now serves as an event and multi-use facility.
and, in practice, cross bolts should be located near the ends of tie beams to obtain maximum strength.
Test results indicate that load capacity of mortise end-walls in tie beams is related both to the wood strength perpendicular to the grain and to the wood shear strength parallel to the grain.
Differences in the strength of wood perpendicular to the grain should be considered in selecting tie beams.
Also of interest was the effect of intermediate tie beams on deflections along with the effect of reinforcement of the wall plates with 3.
In tests with intermediate tie beams, two tie beams (identical to those in the end frames) were added to the two centrally located side wall studs.
Likewise, the sills are linked together at the mid-length points by the tenons of the wall studs supporting the tie beam.
The front and back top plates along with the tie beam provide resistance to lateral forces applied to the walls by the side rafter plates and also locate the position of the tops of the corner posts spatially in a side-to-side direction.
