Experiments on perforated plates subjected to shear

Abstract

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.

Development of Steel Yielding Seismic Dampers Used to Improve Seismic Performance of Structures: A Comprehensive Review

“…It should be noted that Narayanan et al [95,96] investigated the concept of perforated plates. Notably, it was reported that Chan et al [97] in order to develop a new yielding shear panel device, perforated a thin yielding shear panel and welded it inside a short length square hollow section.…”

The Post-buckled Failure of Steel Plate Shear Webs With Centrally Located Circular Cut-outs

“…Their work considered square and rectangular plates with square and circular stiffened and unstiffened cut-outs, with the thin plates being subjected to in-plane shear loading. Narayanan and Chow [5] carried out experiments on perforated plates subjected to shear in order to compare with earlier numerical work. They detailed an analytical solution to determine the initial shear buckling response for plates with central and eccentric holes and, in addition, a method was also proposed to accurately predict the ultimate strength of the thin perforated shear webs.…”
