Remarks 3/5 The main purlin must have an adequate trunnion bearing and be torsional load-bearing. Transverse tensile stress must be verified separately. M1 =1,3 M2 =1,1 F1,Rk . kmod M1 F2,Rk M2 Fv,Rd =min ( ) M1(GL)=1,25 M =1,3 Fv,Rd = Fv,Rk . kmod M M (GL)=1,25 sgsclamp d1 dk Force-grain angle: α = 90° 11.
