| Abstract: | The reference wind pressure in Shenzhen is 0.7kN/m~2,which influences the buildings deeply.The retractable ellipsoidal shell is a steel structure,and the wind load is the control load.So reasonable anti-wind design is helpful to ensure structure safety and save investment.Through the wind tunnel experiment,the wind dynamic character of ellipsoidal shell in all kinds of retracting status is developed,and the results of test and theory are compared. |
