砼准长期抗压强度代替长期抗压强度试验探讨

On Experiment About Replacing Longterm Compressive Concrete Strength with Meta-Longterm Compressive Concrete Strength

在对不同级别荷载持续作用下砼的徐变演化过程试验研究的基础上,提出了“误差足够小”的“准长期峰值荷载”的概念.通过误差分析,探讨了“砼准长期抗压强度”代替“砼长期抗压强度”短期试验法的可行性.

On the basis of the test research by concrete's creeping evolution al process under sustained effect of different levels,the concept about“Meta-lon g peak lead”of that “error is enough petty”is proposed.The feasibility about the short-term test way to replace longterm compressive concrete strength with “Meta-longterm compressive concrete strength”is discussed.
