Experimental Study on Fire Resistance of Building Steel Structure Fireproofing Material

The definition and connotation of the steel structure fire protection material are briefly given, and the relationship between the fire resistance and the HP/A is analyzed and summarized according to the domestic refractory test data of the typical laboratory exposed steel structure. According to the existing specification, the necessity of fireproof protection, the application and basic requirements of the steel structure fire protection material and the necessity of adopting the steel structure fire protection material are put forward, pointing out the existing problems of fire protection technology, exploring other fire protection materials. Reasonable proposal have been given for the fire resistance test standard system, the relevant standards and norms of the system: Develop different fire resistance test methods should be made for different fire situations, and the corresponding assessment methods should be made for practical engineering application. And then the further content that needs to be studied in this field has been pointed out. Although there are many deficiencies that the steel structure fire protection materials transfers from the development, product characteristics, test methods or standard systems and test data to the actual application of the transition, but the actual demand decisions the broad prospects of this area, so it is of great significance to carry out its fire performance test.
