Abstract or Summary
  • Fabricated steel beam specimens with rectangular holes cut in the webs were subjected to load tests to analyze the behavior of the modified section. Beam-depth to hole-depth ratio was in all cases 2.0; however, ratio of hole length to hole height varied from 2.0 to 3.0. The primary instrumentation of electrical resistance strain gages was located at ratios of nominal bending moment to shear for the solid section of 40 and 64. Instrumentation was located with regard to flexural behavior in the tee-sections, rather than the determination of stress concentrations near the hole corners. The approximate Vierendeel method, although not new, is developed for the analysis of beams with web holes; such beams are commonly called Vierendeel beams. Also included is a more precise development of the Vierendeel analogy by matrix analysis techniques. Experimental strain results are correlated with predictions by both the approximate Vierendeel analysis, which is currently used for design analysis, and by the actual Vierendeel analysis. Experimental deflection results are correlated with deflection predictions by the actual Vierendeel analysis. Predictions by the theory of elasticity method are discussed, but due to the complexities of the solution, comparisons with the experimental results are not presented. Tests in which the beam specimens were loaded to failure were conducted to study the type of failure when web material is removed. Failure was a form of lateral instability before the desired failure mode was obtained.
