A new method of analyzing the effect of shear lag in bridge |
| |
| Abstract: | Theoretical method of analyzing the effect of shear lag in bridge structures has some deficiency. Aiming at the deficiency, we introduced the technology of structrral simulation for entire bridge,and analyzed the effect of shear layg by using it as a new method. This paper discussed about the advantages of the new method. As an example, in various cases effect of shear lag in Jinma Bridge was analyzed.Finally,a discussion about the advantages and disadvantages of the theoretical method and the new method were made repectively. Consequently, it provided a new way to analyzing the effect of shear lag in bridge structures. |
