Along with the economic growing and the expansion of the metropolitian area, The highway system is becoming more widely demanded. The construction fee for the straight bridge is always cheaper than the curved bridge, however, in some cases, the bridge system shall be designed as curved due the geometric constraints.
The main purpose for this research is to analyze the lateral load distribution behavior. For the thin-walled box steel girder bridges using the structural matrix theory modeled as a curved grid system. By investigating different type of internal bracing system, we Will be able to realize the lateral load distribution pattern within the steel box girder bridge. The results obtained from this research are also compared with those obtained from the theorem of equivalent beam on the elastic foundation which is often used in the distortional analysis for the steel box girder bridge system. The results finally obtained within this research indicate the developed theory outlined in this research can be pretty helpful for the design engineers. |
