Which risk increases when high-strength concrete beam develops significant shear cracking before steel yields?

💡 Explanation

When shear cracking develops before the steel yields, there's a reduced capacity for ductile behavior due to limited shear reinforcement, leading to potential formation of a diagonal tension crack in beam. Therefore, a sudden and brittle shear failure is more likely to result, instead of creep, bond reduction, or increased corrosion that would need alternative conditions.
