【Abstract】 In order to investigate the effect of temperature (from normal atmospheric temperature to 1000℃)caused by fire on the strength and deformation of concrete,a total of 86 specimens have been performed under different temperature conditions.The content consists of the ultimate tension and tensile,axial tension and elasticity modulus of concrete subjected to fire and then cooled in air.The regularity and mechanism of change in concrete on strength and deformation after high temperature are analyzed,Emphasis is laid on the relationship between temperature and the strength and deformation,and the relevant formulas are proposed in this paper.更多还原
