Which outcome occurs when differential settlement strains the tied columns of a concrete parking garage?

💡 Explanation

Increased shear cracking in spandrels bridges the vertical support columns because differential settlement introduces moments and shears exceeding design, therefore cracking is magnified around joints, rather than improved damping.
