An A36 structural steel (36 Ksi yield strength) W8 x 40 member has been physically cut to 20 ft. long. This member is to be installed as a vertical column that supports a centric, axial compressive design load of 160,000 lb? and can be modeled as one end fixed and one end pinned.
Required:
a. What is the factor of safety against yielding?
b. What is the safe allowable load (lbf) according to Code 1 (AISC).
c. Is this column acceptable to use with the design load according to Code 1 (AISC) and why?
