| Abstract: | The method nonlinear analysis of externally prestressed reinforced concrete simple beam in ANSYS is introduced. Considering both material and geometrical nonlinearity, externally prestressed reinforced concrete simple beams are modeled and analyzed for the whole process of loading until failure at third-point loading, and compared with the experimental ones. The result shows that ANSYS can simulate the whole process of stress. The above modeling method is utilized to analyze the effect of deviator. |
