Study On the High Building Fire Material Behavior and Reinforced Method

The great loss brought by fire is stated,and then analyses the properties of building construction materials such as steel、plain concrete and high strength concrete after the fire,the results indicated that the structural material after the fire remains certain structure strength,in order to decreases the great loss after fire,the remain strength of structural material can fully used,and the reparement and reinforced is used after fire.On the basis of systemly discusses the reparement and reinforced meyhod of concrete crack,this paper pointly introduces a new reinforced method named fibre reinforce plastics of concrete engineering in recent years.At the same time,indicates the shortage of current fire-resistant design,and needs the place of improvement from now on.
