RESEARCH ON THE TEST OF THE TENSILE STRENGTH OF CONCRETE CYLINDER BY TRANSVERSE CUTTING METHOD

Stress distribution at cross section of transverse uniformly distributed load and non-uniformly distributed load applied to concrete cylinder by finite element method is analyzed. The results show that the area of cross-sectional tensile stress exceeds 90 percent, and the value of tensile stress is relatively uniform when transverse distributed load and negate mean distributed load are applied to cylinder.The test shows that nominal transverse splitting strength of concrete cylinder is well correlated to the concrete cube strength and splitting strength of cube and cylinder, especially, above interrelation is more ideal when hold-down central angle is 90b. So both theoretical analysis and test show that concrete strength can be obtained by transverse cutting method.
