Parametric behaviour beam-to-column composite connection using CFS section

Abstract

Steel is a series of iron-carbon alloys with welldefined component ratios. [1]. Steel has several advantages over other materials like concrete and wood. The steel quality could be controlled, produced massively, has high strength in tension, high ductility, and very homogenous and uniform material. Steel is divided into cold-formed steel (CFS) and hot-rolled steel (HRS) [2]. CFS has advantages over HRS, such as lightweight, could be formed for unusual sectional configuration, efficient structural application, and is relatively easy to be modified in the field [3]. Due to its lighter weight, the CFS is beneficial in reducing the weight of the building to reduce seismic activity. Connections are an important part of a steel structure, where a proper design and treatment are necessary to make the structure safe and economic [4].
