| Abstract: | The basic concept of structural simulation Analysis fo r Entire Bridge(SSAEB) is expounded.Combing with a practical example of Danhe New Bridge,which is a largest-span stone arch bridge in the world,that the establish ment process for the SSAEB model of Danhe New Bridge,which is composed by differ ent unit elements including superstructure,substructure and ground base,has been introduced in detail and from the aid of above mentioned model,hence its struct ural analysis calculation is carried out.The results of calculation show that th e technique of SSAEB used to the analysis calculation of long-span stone arch br idge can get more detailed and more accurate results than the results calculated from the traditional calculation theory,therefore the method of SSAEB opens up vast vistas for the application to bridge analysis. |
| Keywords: | Long-span stone arch bridge Structural Simulation Analys is for Entire Bridge(SSAEB) centering of arch truss construction dynamic charac teristics of structure$$ |
