Example of measuring WZ steel band without WRB strapping system: Assumptions: Würth WZ steel band, 1.5 x 60 mm, connected with 12 ASSY 3.0 beam screws, 5.0 x 40 mm, service 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, applicable => 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 the anchorage point The values apply to wood with a raw density of 350 kg/m³ Load capacity design values: Wood: R_,d = R_,k x kmod/gm (with gm for wood = 1.3) Steel: R_{, d} = R_{, k}/gm (with gm for steel = 1.3) It must be assessed whether Würth ASSY 3.0 beam screws should be installed based on the edge distance that must be maintained. These are guidelines for planning. The values must be calculated for each project by authorized personnel.
