A 6m long member consists of a pair of lightest equal leg angles placed back-to-back with fillet welded end connections. Assume that gusset plate thickness is 10mm. The service dead load tensile force is R/4 kN while it is estimated that the service live load force may be applied to a maximum of 20,000 times and may vary from a compression of R/3 kN to a tension of R/2 kN. Design the member using A709M Grade 345 steel and AISC Specification.
