Which mechanical property of steel is most critical when assessing a tower's resistance to buckling under compressive loads?

The mechanical property of steel most critical when assessing a tower's resistance to buckling under compressive loads is the modulus of elasticity, often denoted as 'E'. Buckling is a form of structural instability where a member under compression suddenly deflects laterally. The modulus of elasticity represents the steel's stiffness or resistance ....
