Experimental Research For Complete Stress-Deformation Curve Of Concrete In Unixial Tension

In this paper, the measurement of uniaxial tension complete Stress-Deformation curve for unnotched big-sized concrete specimens by the use of a convenient, self-design tension apparatus was presented , and then the measured curves as well as the factors affecting the shape of curve are discussed.The main work of this paper can be concluded as:(1)The writer illustrates the premise for realization of test for complete Stress-Deformationcurve of concrete and several methods. Then the device stiffness and innovations are introduced in brief.(2)After analyzing and summarizing the 6 affecting factors for the Stress-Deformation curve, this paper provides some suggestions to ensure pereforming the tests successfully.(3) Based on the analysis of complete Stress-Deformationcurve of concrete and experimental results, this paper successfully get the complete Stress-Deformation curve of big-size concrete specimen and make a fitting equation for the processed data.
