Research On The Operational Principle Of The Self-balanced Prestressed Spatial Structure System Assembled With Elements

Based on a new kind of the self-balanced Prestressed spatial structure, this thesis builds up a finite model by using the large-scale finite element analytical software ANSYS, the operational principle related to the duplication, transfer, qualitative change and optimization of internal force of new prestressed spatial structure has been analyzed, the rule of structure changes have been summarized, the characteristics of its own structure have been explored, and the structure has been made to exert its functional fully.Firstly, this thesis introduces the development trend of prestressed spatial structure and application. The basic unit of structure is described. There is a detailed analysis of structural units in the two states under the action of internal forces of the bar changes. And described the basic unit of the self-balanced Prestressed spatial structure stressed the performance of the overall structure. The spatial structure in the two states, through comparative analysis of prestressed structures developed than non-prestressed structure has obvious advantages. Second, introduces the characteristics and the principle of multi-prestressed spatial structure. By using ANSYS, self-balanced Prestressed spatial structure prestressed shell exert secondary prestress and analysize the peak internal force and peak displacement of the node structure. Its system of external loads and structural components under the internal force and displacement were compared. Finally summarize the main result of this text and point out the further work demanded. The conclusion of this topic will give a important theoretical foundation for the application in actual engineering and structural analysis of this system in the future.
