摘要：
In order to analyze the wind-induced response of the gas tank, the areoelastic model of MAN-type dry gas tank was designed and manufactured, which was based on the similarity criterion of wind tunnel tests. The dynamic characteristics of the gas tank model were tested. On this basis, through the areoelastic model test of the gas tank, the wind-induced response of the tank in different load conditions was analyzed in detail. The test results show that the areoelastic model of gas tank can accurately simulate the dynamic characteristics of the prototype structure. The position of gas tank piston has a significant effect on the wind vibration response of the cabinet. The maximum displacement response occurred on the windward side at 2/3 height of the cabinet body when the piston was at the low location. The wind speed has little influence on the displacement response of the measuring points which were close to the location of piston, but had a great influence on the displacement response of those which are far away from the piston. The existence of the piston led to significant reduction of the wind vibration coefficient of the cabinet. Overall, from the top of the gas tank to the bottom, the wind vibration coefficient increased gradually along the meridian. According to the test results, the calculation formula of the wind vibration coefficient of the gas tank is established in this paper. © 2019, Editorial Office of Journal of Building Structures.
