Abstract

![CDATA[Cold-formed steel members have been used extensively in buildings, bridges, railways, high way products and other purposes. Since experimental tests for cold-formed steel members are time consuming and expensive, numerical and theoretical models have emerged as suitable alternatives for solving such problems, and have increasingly been the focus of attention of researchers in recent years. This study involves different aspects of the use of OPENSEES and ABAQUS for macro and micro modelling of cold-formed steel walls. In the first step, a finite element framework using ABAQUS is proposed to show the micro modelling of cold-formed steel walls. In the second step, the simplified framework using OPENSEES is presented to show the macro modelling of cold-formed steel walls. Then in the third step of the study, the two proposed methods are verified against the experimental data and finally, the results are compared and discussed. This study is planned to identify the advantages and disadvantages of the macro and micro modelling of cold-formed steel walls in terms of time of modelling, analysis and accuracy of the results. Results showed that both numerical methods have advantages and disadvantages which should be considered in each analysis.]]
