The cold-formed steel is becoming popular in construction industry because of its various advantages and flexibility in use. The cold-formed steel is manufactured and molded in desired shape at room temperature hence there is a need to study the behavior of cold-formed steel at high temperature. Most of the research has been already done on various properties of cold-formed steel at high temperature like ductility, stress strain curve, etc. but the study on flexural strength and maximum deflection is yet to be done. Therefore in this project the properties like ultimate load, flexural strength, maximum deflection and weight change are studied at temperature up to 5500C. I-section beams were subjected to the various temperatures at 1000C, 2500C, 4000C and 5500C. After cooling the flexure tests were performed on beams in Universal Testing Machine. From the experiments it was observed that, the ultimate load and flexural strength reduces as temperature goes on increasing due deterioration in properties of cold-formed steel at high temperature, while the maximum deflection increases and there is no any weight change of cold-formed steel due to increase in temperature.
