Experimental stresses in wide-flange beams with holes
Experimental elastic stresses were determined from tests of simply supported wide-flange beams that had circular and rectangular web holes located at ratios of nominal bending stress to nominal shear stress ranging from infinity to zero, and were compared with stresses calculated by theory of elasticity and by Vierendeel method; for circular and rectangular holes not exceeding half web depth, elasticity analysis accurately predicts tangential verse cross sections in vicinity of hole, but not octahedral shear stresses at locations other than hole boundary; for rectangular holes not exceeding web depth, Vierendeel analysis predicts bending stresses on transverse cross sections with reasonable accuracy and predicts octahedral shear stress conservatively but does not predict stress concentrations at hole corners.
