4. Wind bracing is to be made of two rolled steel angles grade 350W. The factored tensile load it must carry is a specified dead load of 176 kN and a specified wind load of 220 kN. The M16 bolts will be arranged as shown below (four transverse lines of fasteners). Find the most economical double equal leg angles to carry the load. Assume drilled holes and consider double angles connected at the middle point of the cross-bracing.
