Which risk is amplified when welded steel beams experience cyclic tension loading in bridge construction?

💡 Explanation

When steel beams undergo cyclic tension, fatigue crack propagation happens due to the repeated stress concentrations at weld defects, weakening the material over time and leading to failure. Therefore crack propagation is amplified, instead of corrosion, buckling or shear failure, because these require different loading conditions and structural weaknesses.
