| Abstract: | In order to extend the use of the steel with spiral ribs (500 MPa),the mechanical properties of the steel and the members under flexure reinforced with it are studied in the experiments according to some codes.The steel has excellent ductility and excellent bond with concrete;good properties (strength,cracking and stiffness) and good ductility of the members are showed in the experiments.Through comparing with the results calculated from the code,it proves that the members can be designed according to the current code (GBJ10-89) and that 360MPa can be selected as the designed strength of this steel. |

| Keywords: | deformed steel member under flexure ultimate strength cracking deflection |
