Study On Space Truss Structure Design And Reinforcement

Space truss structure is used widely in industrial and civil architecture, with the passage of time, due to the design of different analysis methods, bar corrosion aging, the change of load and other factors, which makes the grid structure stress performance analysis and research of strengthening schemes for a practical engineering the urgent need. Based on this, this thesis mainly includes the following several aspects of research:(1) Introduces the space truss structure of the research background and research situation at home and abroad, summarizes the existing research results. The grid structure of the form, characteristics and failure reason, commonly used for frame structure strengthening methods are summarized, and analyzed the advantages and disadvantages of various reinforcement methods and suitable scope;(2) Summarizes the space truss structure commonly used structural design method and optimization method and finds out the influence of the design and optimization of factors. according to the structure type, thickness, mesh size optimization design method for space truss structure, the engineering practice to provide optimal parameters, and in response to the three specific examples of projects to be discussed;(3) With a university gymnasium as engineering background, using finite element analysis software ANSYS to build a space truss model, the thesis analyzes static and dynamic characteristics of the space truss structure under load, identify the weak links of the structural design(4) With two paticular space truss structure reinforcement as engineering background, the thesis contrasts the merits and application scope of the casing reinforcement and CFRP reinforcement method, analyzes the reinforcement method, reinforcement measures and processes.
