AN INVESTIGATION OF TWO CURRENT STANDARDS FOR DETERMINING THE WEB-CRIPPLING STRENGTH OF COLD-FORMED STEEL SECTIONS

Abstract

The web-crippling behavior of cold-formed steel (CFS) sections, which have become very popular in the construction industry in recent years, is critical in design. In this study, the following results were obtained from applying TS EN 1993-1-3 and AISI S100-16 standards, which are prominently used to determine the body crushing strength of CFS channel sections and to show the differences in approach. In addition, the strength predictions of these two standards were compared with the predictions of the models created using the finite element method. As a result of the study, it was seen that the TS EN 1993-1-3 standard generally gives conservative results by staying on the safe side. However, according to the effects of finite element analysis of both measures, it is seen that they have very conservative predictions.
