Testing Research For Fire Resistance Of Fire Protection Materials For Steel Structure

This article has simply given the definition,performance of the material for steel structure to fire,formation and testing condition of fire resistance,connected with the datas about fire resistant test for unprotected structural steel from the typical laboratories (internal and external )to analyse and conclude for the connection of fire resistance and Hp/A, clarified the exist advantage and shortage of steel structural buildings as present main buildings,illustrated the necessary of fire protection for steel structure comparing with the present code, put forward the use and general of the fire protection material for steel structure as a passive protection method to fire and the inevitability of using the fire protection material for steel structure ;It has listed a few fire protection materials mechanism, interrelating construction ,existing advantage and shortage , the products tested datas of manufactory, It has showed the problem of fire protection technology in present, discovered the other materials,clarified the research thinking, the content of working,the difficulties of technology ,carrying out program and the objection of working interrelated to fire code for designing,fire resistance testing method ,check and accept in engineering, fire circumstance in use (the five fire type of circumstance) and rescuing methods (a sorts of methods:the water must be considered with the serious effection to structure during the fire) for researching internal task (interrelated to :hydrocarbon fire testing characteristic and method, drawing up the professional standard of high rise temperature testing method for fire protection material for steel structure ,assessing method and standard of fire resisatance of fire resistive coatings for steel structure applied to engineering) ;Mostly it has analysed the seven effection factors(the mains contents are performance of material itself, structural performance of the base, construction method between material and structure ,the level test condition ,the durability of material,type of fire ,the requirement of use ,distinguishing method) to fire resistance,carried out the preparing reseanable proposes to standardilized system ,interrelating standard and code (for three points: fire circumstance to fire testing method,the assessment method standard drawing up to engineering,putting forward to the water hose stream test in standardilized system and fire code),and pointed out the research contents to advance for this sphere (the eighteen datas of assemblies in present fire code for designing have obvious limitation made up the relationship of the resistance of all sorts of assemblies and the fire grade of...
