Linearity and non-linearity stabilty analysis of the long-span Pre-stressed concrete cable-stayed bridges |
| |
| Abstract: | This paper draws a reasonable conclusion by calculation on the stability of the long span pre stressed concrete cable stayed bridges.All of the results are based on a finite element calculating model,in which the cables only tensioned property was simulated and the effects of the pre tension cables and pre stressed reinforcement are included.Furthermore,the effects of the geometric non linearity and material nonliearity are studied together. |

| Keywords: | cable stayed bridges only tensioned pre stressed non linearity |
