Abstract: Through analysis of the steel structure buildings fire protection situation, based on the occupy life of steel structure buildings, the paper put forward that the durability of the protective materials should be considered in the steel structure design phase, and analyzed the illegal operations of fire resistive material manufacturers and steel structure engineering constructors, focused on scene supervision and detection means improvement in the project construction stage, and put forward practical control measures for building acceptance and project management. Based on engineering examples, the key points of steel structure fire protection was proposed, and the corresponding solutions for design, construction, inspection and acceptance was discussed.

Key words: steel structure, fire resistance, building acceptance, fire resistive coating, fire resistive board
