| Abstract: | The secondary-stage annex of Deji plaza,located in Nanjing,is a kind of complicated high-rise building with several irregularities in its structure. A structural system of reinforced concrete frame-shear wall is employed in this structure,with concrete-filled steel tube concrete columns and sectional concrete/steel beams.By means of setting post-pouring zone,using construction measure,adjusting the stiffness of the structure,enhancing the torsion resistance of the structure,and calculating with three-dimensional FEM and time history method,the design problems about super-long structure,structure conversion,obvious effect of torsion are solved.The design of the structure satisfies the need of resisting earthquake. |
