Which failure propagates most rapidly in reinforced concrete columns failing under compression?

💡 Explanation

A rebar buckling cascade quickly causes widespread failure because individual rebar buckles amplify stresses in neighboring bars, leading to subsequent buckling and rapid overall collapse, therefore it is the fastest, rather than slower cracking or creep.
