Which issue arises if concrete rebar placement accuracy deviates excessively from design specifications?

💡 Explanation

When rebar placement deviates substantially, shear force distribution becomes uneven because the intended reinforced regions are not properly positioned, decreasing shear capacity, particularly near supports where shear stress is high. Therfore, reduced shear strength results, rather than enhanced compression, ductility, or ingress resistance which depend on correctly placed reinforcement.
