Tension Theoryĩ Yield on Gross Area Stress eu. Consider L0=100 inch long tension member. P eyL0 D Tension TheoryĨ Yield on Gross Area However, consider how this is affected by the stress-strain conditions. P P=FyA D L Note that residual stress does not affect tension member strength, as ultimate load is not affected and loss of stiffness is not a major factor in tension (as opposed to compression where buckling failure modes are affected). eyL0 D Tension Theoryħ Yield on Gross Area When a member is loaded the strength is limited by the yielding of the entire cross section.

Tension ModuleĦ Yield on Gross Area When a member is loaded the strength is limited by the yielding of the entire cross section. The lowest strength will control design strength. Tensile Strength Strength Limit States: Yielding on Gross Area Rupture on Net Area Block Shear Bearing or Tear-out at Bolts Each of these failure modes will be evaluated individually. Tension ModuleĤ Strength Limit States: Yielding on Gross Area Rupture on Net Area Where varies depending on failure mode. Tension Moduleģ Strength design requirements: Pu Pn (Pa Pn/Ω)ASD Also components of connections and other members. Typically hangers, braces, truss members.
