Which bending risk proportionally rises when steel I-beams experience prolonged compressive stress?

💡 Explanation

Prolonged compressive loads exacerbate initial imperfections, triggering lateral torsional buckling, because this instability causes sideways deflection and twisting, rather than only local yielding like web crippling; therefore, buckling risk increases as stresses accumulate.
