3 cards from this section. Quick, good the night before a test.
What is the plastic moment capacity (M_p)?
Think of yielding.
Define inelastic buckling.
Consider what happens when excessive loads are applied.
What is the primary purpose of verifying a beam column's adequacy?
Think about the meaning of verification in structural design.
True or False: Inelastic buckling can occur even if a beam is made of strong material.
Recall the conditions under which buckling happens.
A W12 120 column is subject to an axial load of 25 kips and a moment of 60 k-ft. Calculate if this section is adequate after verifying all moment capacities and applying moment magnification.
Make sure to calculate B for moment magnification before checking adequacy.
How would the adequacy change if the yield stress of the material increased to 50 ksi? Recalculate the M_p and M_r and determine the adequacy.
Analyze how increasing material strength alters moment capacities.
