| Abstract: | Aiming at the shortcomings of determining descent segment of concrete complete direct tensile stress strain curve at present, based on improved reconstruction of concrete specimen, this paper puts forward a concept of crack resistance reinforcement and a new experiment method. And then the concrete complete direct tensile stress strain curve is obtained by the experiment successfully. Finally , it proves the feasibility of this method. |
