← HistoryWhich outcome arises when suspension bridge anchorage slippage progresses beyond acceptable limits?
A)Cable tension forces redistribute locally
B)Sag-to-span ratio deviates significantly✓
C)Deck stiffening decreases effectiveness
D)Resonance frequency experiences minimal change
💡 Explanation
Anchorage slippage reduces cable tension length; elastic catenary adjusts, therefore the sag-to-span ratio diverges as cables ascend abnormally, rather than redistribute force, diminish deck stiffening, or negligibly change fundamental frequency.
