英文摘要： Man type dry gas storage tank is a kind of important and superhuge structrue, which is usually used to store combustible gases, save resouces and protect enviroment. Those type of tanks are widely used in metallurgical, petrochemical, municipal and other industries. The main research object of the project is to develop the wind design theory of large Man-type dry gas tank structures. There are lots of topics to discuss, involving the dynamic character considering the internal piston movement, the buckling problem under the static wind and dynamic wind loads,the shape coefficient and the equivalent wind load of thin-walled structures, the gas tank aeroelastic model design method, simplifid large gas tank calculation method about wind loads which is suitable for the engineering design, etc. Based on existing large gas tank construction projects, theoretical analysis, experimental studies, numerical simulation and other means are employed to analyze vibration response of large Man-type dry gas tank due to wind loads. The reliable, valid theoretical basis will be developed to design this type of structure. Therefore, this project has important theoretical significance, value and social and economic benefits.
