← TechnologyWhich limitation arises because concrete creeps under sustained compressive stress in prestressed beams?
A)Increased shear from diagonal tension
B)Reduced camber due to steel relaxation
C)Higher deflections over service life✓
D)Lower buckling resistance from end restraint
💡 Explanation
When concrete is subjected to sustained compression from prestressing, concrete creep occurs because of slow internal deformations over time, leading to increased deflections. Therefore higher deflections occur over service life, rather than reduced camber which involves steel losses, or altered forces that dictate shear and buckling.
