← TechnologyWhich risk increases when significant yielding occurs in a steel beam during construction before concrete curing?
A)Reduced long-term load capacity✓
B)Increased susceptibility to corrosion
C)Higher thermal expansion coefficient
D)Lower resistance to fire damage
💡 Explanation
When a steel beam yields before concrete curing, stress redistribution occurs because the steel permanently deforms, losing its composite action with the concrete resulting in uneven stress distribution once load is applied. Therefore, reduced long-term load capacity results, rather than corrosion, thermal issues, or fire resistance problems which hinge on different failure modes.
