摘要
通过测定不同强度等级试件在不同龄期下的抗剪强度,总结抗剪强度的发展变化规律,进而提出混凝土抗剪强度参数及适宜的混凝土抗剪强度测定试验方法。采用直剪方法得到混凝土剪切强度,并对其与混凝土抗压强度、劈裂抗拉强度之间的关系进行研究,为混凝土剪切强度的研究提供参考依据。
Testing the shear strength of the specimens in different strength grade and ages, the development law of the concrete shear strength is expounded.Then the parameters and appropriate test methods of concrete shear strength can be presented.And direct shear method is used to gain concrete compressive strength and the splitting tensile strength, studying the relationship among them, which can provide reference for the study of the concrete shear strength.
