| Abstract: | The movable service tower in satellite launch centre is a steel structure tower which serves satellite launch.The tower has a irregular plane,complex modle and can be moved.The design method of the tower structure is presented with programme SST.The result of calculation indicates that the control load is wind load.After having been used for 20 years,the dynamic properties of the tower are examined.Based on operating characteristic,the status of dynamic properties are analyzed.The result indicates that the structure is in good state. |
