| Abstract: | Based on the plane formula of Cranston method to modify stiffness matrix, a new method called extended Cranston method to establish elasto-plastic matrix of space beam element is presented, where the program of space stability ultimate load nonlinear analysis of concrete bridge is also developed. The reliability of the present method and program tested by the good agreement between the analysis results and the experiment results from references proves that the present method can be utilized to calculate the space stability ultimate load of concrete bridge. 4figs. ,10refs. |
