Generally molded cylinders are used to determine the splitting tensile strength of concrete, but the strength is often influenced by supplementary bearing bar or plate. Then we tried to measure the tensile strength using portions of beams broken in flexure. First we chose some loading methods and investigated them by stress analysis. The stress analysis indicated a loading method by which the specimen had good stress distribution. Second we examined the loading methods and bearing bars by experiments. The experimental results showed that by the loading method mentioned above and by a kind of bearing cylinder the tensile strength could be known using portions of beams broken in flexure. In this paper the testing method we proposed is explained in detail to determine the splitting tensile strength, which was theoretically reasonable and snowed good experimental results.
