*capacity R_1,k is calculated from the nails capacities but mustn’t exceed the maximum value.

n = effective number of nails in the row according to Eurocode 5 – 8.3.1.1 (8)

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 R_1.k is: R_{l.k= min} (R_1.st; R_upper; R_lower )

Where:

R_1.st: the maximum characteristic value tolerated under tensile load as specified in the table above. R_upper: the resistance of the group of fasteners in the upper wall Rlower: the resistance of the group of fasteners in the lower wall R_upper = n_ef.upper x R_lat.k  R_lower = n_ef.lower x R_lat.k

Where:

n_ef.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.
