A Practica; Analysis Method for Lateral Stability of Open Tied Arch Bridge |
| |
| Abstract: | In this paper, an approximate analytical solutionfor lateral stability of open tied arch bridge is developed. The method is based on approximate displacement functions and initial stress method. The results of the analytical method are shown to agree quite well with those of the finite element method, and the method will be quite convenient to use. |
