THE INFLUENCE OF THE ADJACENT SPANS ON THE ROTATION CAPACITY OF BEAMS,

Abstract

This report contains a description of four experiments on wide flange beams in which the yielded zone extended over three unbraced fields. These experiments were performed to determine the post-buckling strength of beams in which the spans adjacent to the critical segment were fully yielded. It was found that for the same unbraced length, beams with completely yielded adjacent spans delivered only about 30% of the rotation capacity of beams with elastic adjacent spans. For effective unbraced lengths of 40r sub y or more, failure was due to lateraltorsional buckling while for shorter beams failure occurred by local buckling. (Author)
