Temperature effect analysis of pre-tension and deformation characteristics of planar membrane structure

In this paper, the planar membrane structure of an engineering example is analysed theoretically from the variation of pre-tension and membrane surface deformation with temperature. Then ANSYS software is used to analyse the pre-tension changes of the membrane structure and the membrane surface deformation with the uniform load under different temperatures (-50 similar to 70 degrees C) for the membrane structure. The trend image of pre-tension and membrane surface deformation with temperature was obtained, and the minimum value of pretension of the membrane structure was obtained according to the relevant regulations. According to the variation law of pre-tension, the pre-tension selection scheme for the installation of planar membrane structure is summarized, which provides some references for the determination of pre-tension in the installation of planar membrane structure.
