He Zhijun' Hu Yin' (1.Architectural Design Research Institute of Tongji University Group)Co.Ltd.Shanghai 200092 China; 2.School of Civil Engineering Tongji University Shanghai 200092 China) Abstract:In this paper the effect of construction of hanging curtain wall support structure (CWSS)of Shanghai Tower was mainly discussed.On the basis of construction simulation analysis preset deformation and additional internal forces was studied.Studies show that because of the nonuniform stiffness of MEP floor inhomogeneous deformation of CWSS is significant preset is required to ensure the correct shape.And also paratively large internal forces are required to give fuller consideration as a result of vertical pression of main structure.
