Numerical Analysis in Development of a Cross-Sectional Model of the “C” Profile Cold-Formed Steel SNI-1729:2015

Abstract

Lightweight structural steel profiles are often called cold-formed steel profiles-steels are formed by means of cold rolling of thin steel sheet so that the mass of steel profiles are extremely light. Because it has a thin plate thickness and mass of very light steel profile lateral stiffness is relatively low and is determined by the shape of the cross-section profile. This paper will discuss the development of a cross-sectional model of profile "C" size of 70 mm in the cold-forming steel SNI 1729:2015 is done numerically with the help of software. The analysis was carried out on the cross-sectional shape of the SNI 1729:2015 standard and the results of the development of the cross-sectional shape. The analysis was conducted by reviewing the deflection that occurs in the lateral direction on rod dimensions and the same type of loading. Results of the analysis show that in the cross-sectional shape of the development results there is a decrease in the lateral deflection, this shows that there is an increase in the lateral stiffness of the lightweight steel structure profile after the development of the cross-sectional model.
