Efficiency of structure in fire is depend on variety of factors such as material degradation of material at elevated
temperature restrain rigidity of fire surrounded members.it is important to understand structural response to fire in order to face
minimum damage of structure and in order to select appropriate fire-resistance measures. It is not feasible to carry out
experiment on real structure as it requires space, time, fire control meseares as well as money. Therefore using of finite element
based software’s like ANSYS is always best option instead. In this paper the properties of concrete and steel that influence
behavior of structure at elevated temperature have been examined
