Which risk increases when a pre-stressed concrete beam experiences sustained overloading beyond its design capacity?

💡 Explanation

When a pre-stressed concrete beam is overloaded, the concrete experiences higher compressive stresses which lead to increase creep deflection because of long term deformation of concrete under sustained load, hence camber loss. Increased creep and camber loss results rather than corrosion, reduced damping, or decreased bond which involve different factors.
