FAILURE TESTS ON BEAMS WITH ECCENTRIC WEB HOLES

Laboratory tests on two W16 x 45 A36 steel beams and three W16 x 40 A36 steel beams with reinforced eccentric web openings are described and summarized. The principal test parameters were the opening size and the amount of opening reinforcement. Tests were carried to failure and the deflections modes of failure, and ultimate loads recorded. The results of inelastic finite element analyses of the test beams are also summarized. It is concluded that both the experimental and finite element results are reasonably consistent with the four hinge failure mechanism assumed in a previously developed ultimate strength analysis, and that this ultimate strength analysis provides an adequate prediction of the strength of beams with reinforced eccentric web openings.
