| Abstract: | By using three dimentional photoelastic frozen stress method, the stresses in a bridge of continuous beam type and with net structured tie rod archs are analyzed. Different working conditions for the bridge are considered. The results are helpful for optimizing the engineering design. |
| Keywords: | photoelastic method of 3D principle stress trajectory bridge of continuous beam type and with net structured tie rod archs |
