ReidBrace is an off-the-shelf system that provides design engineers and constructors with an economic solution for tension bracing of structures, tie-back applications and temporary works bracing. ReidBrace utilises ReidBar, a user friendly continuously threaded 500 grade reinforcing bar as the tension member. ReidBrace is a unique system that is as easy as screwing on a thread to install, minimising fabrication time.

32mm ReidBrace

32mm was not included in the test program, due to machine capabilities in the testing facility, therefore, 32mm ReidBrace should be designed elastically (µ = 1). ReidBrace 32mm components exceed the minimum yield of 32mm ReidBar.

Test data has shown that the stiffness of the ReidBrace System is different from the theoretical Young’s Modulus of steel; in order to obtain more realistic results from the FEM model, it is recom-mended to adopt the proposed Equivalent Elastic Modulus.

Equivalent Elastic Modulus

Diameter Equivalent elastic modulus

12mm 160000MPa

16mm 145000MPa

20mm 140000MPa

25mm 135000MPa

32mm 125000MPa

Connection design

• Refer to chapter 9 of NZS3404 or AS4100 (or relevant standard) when designing connection detail

• Performance of ReidBrace is based on the cleat/ connection detail exceeding the ReidBrace system capacity

• Gap between the fitting and the steel cleat on each side shall not exceed 3mm

• Bolt and nut should be installed so the underside of the bolt head and the nut are in contact with each ReidBrace fitting

Preloading Bracing SystemTension on structural bracing span should meet L/100 sag criteria.

Ref: HERA report R4-80 section 3.3.2 Woolcock, S T and Kitipornchai, S; Tension Members and Self-Weight; Steel Construction, Vol. 19, No. 1, May 1985, Australian Institute of Steel Construction.

Overstrength FactorOverstrength loads have been determined following the principles of NZS3404, based on the experimental testing undertaken. The overstrength is to be resisted by the design capacity of secondary elements of the steel system, in a capacity designed system.

Installation Special Cautions:The ReidBrace must be centralised on the bracket to ensure central loading force.

Check if gap on each side is less than 3mm. Install washers proportionally if gap on each side exceeds 3mm.
