摘要
通过对高强混凝土 (C60 ,C80 )高温时力学性能的试验研究 ,得出了高强混凝土立方体抗压强度 ,峰值应力 ,峰值应变及弹性模量随温度的变化规律 ,并与普通强度混凝土 (C3 0 )高温力学性能进行了比较 。
The experimental research on the strength and the deformation of the high?strength concrete (HSC)at elevated temperature is conducted An attempt is made to study the mechanical properties of HSC at high temperature It is compared with that of the normal strength concrete The test results show that the compressive strength of the HSC is decreased quickly when the temperature over 400℃ The rule of the compressive strength,peak stress,peak strain,and the modulus of elasticity of HSC at elevated temperature are obtained At last ,a complete curve of compressive stress?strain for the HSC at elevated temperature is proposed in the paper
