Study On The Transformation And The Stress Of The Multi-span Continuous Beam Landscape Bridge

Along with the development of economic level,great deals of Landscape Gallery Bridge are built,they are used to decorate environment and are beneficial to people’s living,and some of them even become symbolic buildings.Landscape Gallery Bridge have a new chance to develop.So far,those related materials about Landscape Gallery Bridge more focus on the development of building styles and its culture,but less notice its mechanical property.Therefore,it is necessary to research the deflection of Landscape Gallery Bridge when it start to run.Through searching various books and articles,not only does the essay summarize the originality and advancing courses of continuous beam landscape gallery bridge,but also introduces its characteristics and classifications,as well as theoretical explains related elements of affecting the deflection and stress in operation.The thesis bases on the background of continuous beam landscape gallery bridge in BaoJi city to build model.In the aspect of deflection,it mainly analyzes and considers effects of two parts in concrete shrinkage and creep and the construction load in the second phase,especially explaining the relationship between the construction load in the second phase and starting operational time and time limit for the project of the upper gallery structure and the load method and the location of the construction load in the second phase and the deflection of the Landscape Gallery Bridge.In additionally,through sorting out the deformation inspection data for several years,the thesis compares deflection of the continuous beam landscape gallery bridge counted by the finite element software and the actual deformation,and then indicates the basic law of the deflection for continuous beam landscape gallery bridge.At last,it discuss and present some ways to improve the strained condition of continuous beam landscape gallery bridge.
