【摘要】 文中将国内外一些学者对高温后混凝土力学性能的试验结果进行了对比分析,得出如下结论:高温后无约束高强混凝土与无约束普通混凝土、高温后约束高强混凝土与约束普通混凝土的力学性能随温度的变化规律均基本一致。通过本文高温后无约束高强混凝土与文献[8]的试验结果的比较,二者所得规律基本相同。更多还原

【Abstract】 After analyzing the experiment results presented in this paper and other literatures, we can get the following conclusions: 1.The law that the mechanical behavior of unconfined HSC changes with the temperature is the same as that of NSC after the temperature becomes high. 2.The law that the mechanical behavior of confined HSC changes with temperatures is the same as that of NSC after the temperature becomes high. 3.After comparison,the law of the mechancical behavior of HSC after high temperatures presented in this paper is roughly the same as the experiment results stated in reference.更多还原
