Experimental Investigation of Cold-formed Steel (CFS) Channel Material at Post Elevated Temperature
Cold formed steel (CFS) is the popular structural material used in the building nowadays due to a variety of advantages in its manufacturing, fabrication and erection. The main objective of the study is to study the properties of the CFS at post elevated temperature. When this material is exposed to fire the steel material properties are degraded. Therefore, it is important to predict the degradation of material properties of CFS after exposed to elevated temperatures. The microstructure test was found that after exposing to 1,000 °C temperature compared to normal CFS, the composition of eight elements in CFS has increased as Carbon, C is the highest at 129.7 %, meanwhile, thirteen elements are decreasing as Silicon, Si is the highest at 80.6 %. Results from tensile coupon test of post elevated temperature CFS shows that the cold formed steel that expose to fire may regain its yield strength within 10–60 % for range temperature 400–1,000 °C when compared to the Class 4 steel in EC3-1-2. The pattern of the reduction factor of CFS is similar to the hot rolled steel S460.
