| Abstract: | The CIEF building,177.3m high,is with steel frame-reinforced concrete tube structure.In order to reduce the adverse influence on the structure during construction process,which are caused by concrete shrinkage and creep,difference in temperature and wind load.During construction process,structure deformation is analyzed and calculated,and the pre-control and corrective measures are used to ensure the accuracy of structure construction. |
