Which performance loss occurs when temperature cycling weakens rebar?

💡 Explanation

Reduced tensile stress support happens because temperature variations cause differential expansion leading to alternating expansion & contraction cycles in the rebar/concrete matrix, which weakens the bonding strength at the interface therefore tensile stress capacity reduces rather than fatigue since steel fatigue needs tensile stress presence.
