Characteristics of secondary flexures in uniaxial tension test of concrete

摘要: In the uniaxial tension test of concrete, inevitably some secondary flexures occur. However characteristics are not well understood among others because complexity performing without flexures. this paper in which minimized, by a specially developed device, compared to tests where left develop freely. Experimental results and theoretical calculations shown for influence on load-deformation curves, tensile strength strain energy specimen. Plural grow finally plural cracks were also analyzed concerning an experimental result. It is concluded that should be they produce considerable error curve strength. Furthermore, controlled continuously during minimized state unstable equilibrium And can only using notched specimen occur un-notched
