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∼70 °C) for the membrane structure. The trend image of pre-tension and membrane surface deformation with temperature was obtained, and the minimum value of pre-tension 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.
