Abstract
  • This thesis investigated the methods of failure in the webs of built up girders. The beams had rectangular holes five and one-half inches wide and seven and one-half inches high with rounded corners in a web fourteen inches deep between flanges. The longitudinal position of the hole edge varied from four inches to sixteen inches from the support. The results of the test were compared to analytical analysis for failure by column action, plate buckling and shear in the web. Failure occurred by local crippling in the web in the test beams with holes four and eight inches from the support. The test beams with holes 12 inches and 16 inches from the support failed by yielding of the web under the applied load. The test results indicated that further study is needed of local stress effects at the edge of the holes.
