Abstract

"This investigation deals with a series of column tests of aluminum I-sections which have a perforated web. Specifically, the tests show that the weight is decreased without decrease in strength. Several basic assumptions are made in the design of a column. The physical action of a column is idealized in the derivation of formulae which will predict within reasonable limits the load which the member will sustain. In a given installation of non-homogeneity of material, kinks, uneven bearing, lack of symmetry due to riveting or welding, stress concentration and many other disturbing factors not in agreement with these assumptions may be present. This investigation will deal with one of these factors, namely, the effect upon column action of a discontinuity present in the cross-section of a column. The scope of the investigation is limited to an I-section. The type of discontinuity is a circular hole placed at the mid-point of the web of the I-section. The objective is to determine if the conventional design formula used with this material is applicable to this non-ideal column"--Introduction, page 1.
