| Abstract: | In this paper, the experimental results on the model of double slope roof membrane structure in the wind tunnel are presented. The differences of coefficient of wind pressure between models with sealing and opening on all sides are compared in all wind directions, and the change in coefficient of wind pressure is discussed when door is opened abruptly. These results are analyzed, and the basic data of wind resistant design of membrane structure and its application are provided. |
