← TechnologyWhich buckling risk notably decreases when pretensioned tendons yield?
A)Lateral torsional beam instability✓
B)Column critical compressive failure
C)Local web crippling potential
D)Rebar stress exceeding yield strength
💡 Explanation
Lateral torsional beam instability decreases because yielding tendons increase the beam's flexural stiffness before concrete cracking via increased neutral axis depth and resisting torque; therefore lateral movement is reduced, rather than compressive or local web failures.
