DOI: 10.1007/s11012-017-0763-5
Abstract: Although the manufacturing process of structural members has been improved over the last decades, inherent geometric imperfections in slender beam-columns cannot be avoided altogether. Such imperfections largely affect the buckling behavior of the beam by… read more here.
