Recently, practical application of high tension bar is attempted. The main object of using high tension bar is strengthening of material property and decreasing of steel amount. If using high tension bar which is not a definite yield strength，according to strain ratio of high tension bar tensile and compressive dominate mode ciearly, there being a possibility dividing becoming difficult. Specially, Providing steel ratio of balanced destruction is very difficult. In this study, high tension bar to apply to flexural member and the behavior experiment bending after one, will consider high tension bar the application possible standard of existing.
