Which risk sharply increases when concrete column ambient temperature rises beyond design specifications in a bridge?

💡 Explanation

When exceeding design temperatures creep accelerates because increased temperature reduces concrete viscosity, magnifying time-dependent deformation under sustained load stress. Therefore, creep related stress relaxation happens rapidly, rather than effects involving chloride diffusion, freeze-thaw cycles, or rebar stability that change slowly at elevated temperatures.
