Weak-axis flexural buckling of cellular and castellated columns

摘要

Cellular and castellated members are usually produced by performing cutting and rewelding operations on a hot rolled I-section member. As illustrated in previous work, these operations will influence the residual stresses present in the members in a manner which is detrimental for the flexural buckling resistance. Up to now, this has not been considered in the limited amount of literature concerning the flexural buckling resistance of these members.
