Windbracing Strap
BAN09 windbracing straps can be used for anchoring and bracing of roof constructions. The engineered "strong-holes" ensures a very light 0.9 mm strap with the same capacities as a 2mm strap. The thin material makes the strap easy to lift and handle on the job site. And it is easy to cut with metal shears.

The maximum characteristic value tolerated under tensile load corresponds to the plate's maximum tensile strength. The fasteners must be checked separately using EN 1995-1-1. The characteristic resistance of an BAN fixing band assembly under tensile load R1.k is: Rl.k= min (R1.st; Rupper; Rlower )
Where:
R1.st: the maximum characteristic value tolerated under tensile load as specified in the table above. Rupper: the resistance of the group of fasteners in the upper wall Rlower: the resistance of the group of fasteners in the lower wall Rupper = nef.upper x Rlat.k Rlower = nef.lower x Rlat.k
Where:
nef.upper: the effective number of fasteners in the upper wall nef.lower: the effective number of fasteners in the lower wall Rlat.k: the strength of the chosen fastener
Example: BAN094025 joining two CLT walls with an intermediate floor. The aim is to determine the fixing band's load-bearing capacity when subjected to tensile forces. The nailing pattern shown below is used. The following table provides the characteristic strength values.
