The truss is loaded with service loads (Dead load and Wind Load) as shown in the figure. Members DE is welded to a 10 mm thick gusset plate using maximum size of fillet weld and E70 electrodes (FEXX=485 MPa) also shown in the figure. All steel is A36 (Fy= 250 MPa and Fu = 400MPa). Use LRFD and the Metric Sizes Tables for Angles in the ASEP Steel Handbook.
