Structure Analysis of Cold-Formed Steel Roof Truss Post Office Branches Loa Janan

Abstract

Steel is one of the most widely used construction material for structural systems in modern construction. In recent years, Cold formed steel (CFS) sections-which is being another major type of steel sections and found to be an alternative to the familiar Hot rolled steel sections. The purpose of this research is to choose the best CFS products in terms of strength and safety which use for Loa Janan post office. This study begins by collecting primary and secondary data. Then look for references in CFS products in the field. In this study there is 4 CFS brands (Taso, Cici, Truss, and Kaso product). Than the sample of product will be testing in the laboratory. The loading is carried out guide [1]. Than to analyse of the CFS frame use [2]. For model using SAP 2000 application. The material used in this study were steel profile C 75 75 0.75 to tension members. From the results of the analysis. it can be concluded that of the 4 steel materials being studied all can withstand the load. However, the CFS brand Taso has the highest maximum stress of 46.27 KN. while the smallest Truss brand is 0.17 KN.
