“…As before, an approximate empirical relationship for obtaining a quick estimate of the buckling coefficients, for a plate containing a circular or square hole in the tension diagonal is suggested below (11) where A , = area of the eccentric (circular or square) hole. Figure 19 compares the numerical values (using the finite element method) and the predicted values by the approximate relationships suggested in equation (1 1) with the experimentally observed values.…”

Experiments on the buckling and ultimate capacity of thin-walled steel web plates containing circular and square cut-outs are reported. Some 64 tests were carried out on plates containing either one or two holes. The parameters varied included the size of the hole and the eccentricity of the location of the hole.For an increase in the eccentricity of the hole, the shear buckling coeficient increased when the opening was located in the compression diagonal and decreased when it was in the tension diagonal; it was found to be insensitive to the location of the hole, for small openings.Approximate formulae are suggested in the paper for computing the shear buckling coefficients for plates with central and eccentric holes, and are suitable for use by designers. A method of predicting accurately, the ultimate capacity of the web is presented.

This paper describes a data-base approach to the ultimate compressive strength of unstiffened plates loaded in uniaxial compression. A total 793 individual test results of plates is surveyed and stored into the Numerical Data-Base for the Ultimate Strength of Steel Structures (NDSS). Statistical assessments are made for the plate test results to compare with the available strength formulas. And the effects of initial imperfections such as residual stress and initial out-of-flatness are discussed. Then strength formulas are proposed for two groups, "with residual stress" and "without residual stress", to explain more accurately the test data.
