LOCAL SHEAR BUCKLING IN COLD-FORMED STAINLESS STEEL BEAM WEBS. IN: STRUCTURAL STABILITY RESEARCH COUNCIL. 1990 ANNUAL TECHNICAL SESSION, STABILITY OF BRIDGES, ST. LOUIS, MISSOURI, APRIL 10-11, 1990

An experimental study on the behavior of cold-formed stainless steel beams subjected primarily to shear is presented. The purpose of this investigation was to obtain the necessary information on the local shear buckling strength of stainless steel beam webs. The materials under investigation were stainless steels Type 304, 430 and a modified Type 409 designated 3CR12, a corrosion resisting steel. The stress-strain curves of stainless steels differ from that of carbon steel in that stainless steels yield gradually. Therefore the results obtained in the investigation differ from those results obtained from testing cold-formed carbon steel beams.
