Which outcome occurs when a prestressed concrete reactor containment building experiences ground subsidence?

💡 Explanation

Increased tendon stress occurs because differential settlement compromises the isostatic prestressing. The altered soil loads transfer via the base slab applying uneven loading; therefore, stress concentrations increase rather than uniform distribution given the mechanical equilibrium shift.
