The Critical Weakness of the I-Beam

This video explains the major weakness of the "I-shape". The main topics covered in this video deal with local and global buckling as well as torsional problems around I-beams. We compare different shapes of beams and analyze their behavior under eccentric loads. The inability of the I-beam to carry torsional loads is illustrated through a numerical example.
