| Based on a fundamental understanding of the history of the development of transferring structure, a basic comparison was made between different types of transferring structure, whose technique parameters and advantages and disadvantages were summarized roughly. After the knowledge preparation carried above, I began to deal with a large and complex project in which a properly designed transferring structure plays a key role in the whole building. First I compared different feasible transferring structure, and it ended that the inclined column structure is the most proper one for this project. Then structural mechanics analysis was carried for primary design using PKPM/SATWE, which is one of the most popular design code in the country. Because the transferring structure type is not very common, and it is so important for the whole building, a detailed analysis was carried to give more information about the working status of the local transferring joint. The analysis is based on finite element method using one of the most pioneering FEM code ANSYS. For the application of ANSYS in R-C structure engineering, I made a fundamental introduction of FEM theory and some important aspect of ANSYS, like its working procedures, parameter settings, etc. From the ocean of ANSYS results data, I focused on the most illuminating items, like the internal force of two different types of material, the relation between internal force and loading, the relation between internal force and the node position in the structure, the translation at the top of the structure and its influence on the shear walls above. From these aspects a conclusion was safely made that the design of the transferring structure is successful.In the end, some design aspects deserve special attention in the design of inclined column transferring structure were presented, and this type of transferring design was recommended. Some comments were also made on the application of the ANSYS in the civil engineering field. |
