Analysis And Optimization On Structure Of Chongqing Style Intelligent Multi-span Greenhouse

This article introduces the development situation of the greenhouse in our country and others, at precent, the author exoatiates the importance and necessity of Multi-Span greenhouses on the side of structure optimization in the condition of Qiongqing city and the development situation of the modern greenhouse in our country.According to the theory of engeering mechanics and greenhouse structure normative, the loading of multi-span greenhouse was analyzed, loading combination was considered,calculation model of multi-spans greenhouse was established, and the calculative model was calculated by finite element analysis software. Discussing the general process of structure optimization, and make sure the general method to the special situation of the greenhouse structure. Optimize the greenhoure structure, and check the loads of the greenhouse which has been optimized. The result point out that intensity and stability of greenhouse structure is enough in the condition of cutting down the material quantity of the greenhouse because of greenhouse structure optimization.A method for analyzing large-size multi-spans greenhouse was put forward in my paper.The structure of multi-spans greenhouse was analyzed this method, and optimized. Finally, we can make an optimum design which has a rational internal force and arrangement, whichcan economize material, which is easy to be constructed and can popularized widely.Finally, design out a kind of reasonable multi-span greenhouse which is easy building and using less material.
