← TechnologyWhich outcome arises when eccentrically loaded support columns experience excessive base rotation?
A)Decreased buckling load capacity✓
B)Increased shear stress resistance
C)Enhanced material compressive strength
D)Improved damping of vibrations
💡 Explanation
Eccentric loading introduces bending moment to the _columns_, leading to _reduced cross-sectional resistance_. This activates the _p-delta effect_ weakening against buckling failure during rotation under _eccentric forces_. The axial load intensifies because of the deflection rather than uniform compression.
