With

n: the number of nails

R_lat,k : Shear capacity of the fastener

Installation

Fixing

Nail plates are commonly used with:

CNA nails Ø4.0
CSA screws Ø5.0

Installation

The performance values stated in the table refer to the nail plate’s maximum tensile strength. The fastener capacity must be checked separately in accordance to BS EN 1995-1-1.

The characteristic resistance of an NP nail plate assembly under tensile load R_1.k is:

Rl.k= min (R_1.st / k_mod; R_upper; R_lower)

Where:

R_1.st: the maximum characteristic value under tensile load as specified in the table.
R_upper: the resistance of the group of fasteners in the upper wall
R_lower: the resistance of the group of fasteners in the lower wall

R_upper = ne_f.upper x R_lat.k R_lower = n_ef.lowerx R_lat.k

Where:
