← TechnologyWhich risk increases when load eccentricity exceeds the core distance in a concrete support column?
A)Tensile cracking develops in concrete✓
B)Shear failure occurs along rebar
C)Buckling strength increases dramatically
D)Carbonation rate reduces substantially
💡 Explanation
When the load eccentricity exceeds the core distance (kernel) of a concrete column, tensile stresses develop because the entire cross-section cannot remain in compression, leading to cracking. Therefore tensile cracking is incentivized, rather than shear failure, increased buckling strength, or a reduced carbonation rate, resulting from completely distinct structural conditions.
