Abstract
Featuring for non-linear stress-strain relation, the behavior of thin-wall plates differ widely from stainless steel to carbon steel, which plays a basic role in relevant researches. This paper describes the development of FE models for analyzing stainless steel plates in compression which is based on the existing results of Rasmussen’s test, as well as the strength curve achieved by such advanced FE models. The explicit strength equations and design method are proposed for determining the local buckling strength of stainless plate and cold-formed square and rectangular hollow section in compression. It is shown excellent agreement with test results achieved by using Quach’s model as stress-strain relations in FE models. The proposed design method also exhibits reliable results, which could be used in structural design of stainless steel plates in compression.
