Measurement example steel strapping WZ without WRB tensioning system: Assumptions: Würth steel strapping WZ 1.5 x 60 mm, connection with 12 ASSY 3.0 joist hanger screws 5.0 x 40 mm, usage class 2, load duration class: "short", load F_d = 15.0 kN Calculation: R_1,dWood: 12 pcs x 2.13 kN x 0.9/1.3 = 17.7 kN, decisive => 15.0 kN/17.7 kN = 0.85 < 1.0 R1,d Steel: 23.6 kN/1.3 = 18.15 kN
Note: n = number of nails at anchor point Values apply to a wood raw density of 350 kg/m³ Design values for load-bearing capacity: Wood: R_,d = R_,k x kmod/gm (with wood gm = 1.3) Steel: R_,d = R_,k/gm (with steel gm = 1.3) It should be assessed whether Würth ASSY 3.0 joist hanger screws should be installed based on the edge spacing which is to be maintained. These are guides for planning purposes. The values must be calculated for each project by authorised persons.
