Different Insulation Technique for Fire Protection of Industrial Steel Structure

The construction of steel high rise building is proved to be more economical than those made of RCC. But one of the major drawbacks of steel is susceptible to fire as metals are good conductor of heat and electricity. On the other-hand, office buildings are equipped with so many accessories which are vulnerable to fire. When exposed to fire, commonly used steel section loses, some of its mechanical properties due to that elongation, deformation, buckling, or any other stresses are generated. Heavily loaded steel loses it designed safety margin at a temperature around 220 °C—regardless the grade of steel. Majority of the research works carried out in this field came out with different techniques to protect a steel structure from fire by means of making it fire resistant internally or externally. Some researches came up with different modelling and analysis tools to develop the fire resistance of structural steel. In this present paper, we presented the different alternatives discovered so far to improve the performance of steel on fire and behaviour of different structural members under various loading conditions are explained.
