| Abstract: | The skewed bending bridge model is set up by using the calculation method of the structural finite element, taking a skewed bending bridge as the engineering background and utilizing the large-sized general software ANSYS. It is to calculate the structural deformations of the different curve radiuses under the constant loading action by the parameter variation process. It is to contrast and analyze the law and reason of its variation provided to the engineering design and construction departments for reference. |
