A C15x50 (d=381mm and tw=18.19mm) tension member is to be connected by fillet welds to a 20mm thick gusset plate. The gusset plate is of A572 Grade 50 steel with Fu=448MPa and the tension member is A36 with Fu=400MPa. The weld is a 12mm fillet weld with E60xx (FExx=415MPa) electrodes. Assume tension failure on connecting members is not a problem. Two equal longitudinal welds of 356mm each at top and bottom flanges of the channel and one full transverse weld will be provided to secure the connection. Calculate the maximum service deadload in KN that the connection can carry considering shear on weld metal if the liveload to deadload ratio is 2.3. Use LRFD. Express your answer in 2 decimal places.
