Compression capacity of steel sections

Output:

Definitions
• ϕ = Resistance factor
• Fy = Yield strength of steel
• E = Elastic Modulus
• A = Area
• I = Moment of Inertia
• k = End restraint factor
• L = Column height (ft)
• P_n = Nominal compressive strength
Calculate the radius of gyration about x and y
• in
• in
Calculate the governing slenderness ratio, kL/r
Calculate the factored compression resistance
• ksi
• ksi
• kip
User Notes:
User notesThis calculation is not valid for sections with slender elements, sections that are not doubly-symetric, cruciforms, and nonprismatic sections. klr should be less than 200.
