Structural design and optimization of a super high-rise building located in 9 degree seismic fortification area in Uzbekistan
For the super high-rise buildings in the 9 degree seismic fortification area,their structural design is basically controlled by the seismic action,so the seismic design is particularly important.The technology of seismic energy dissipation for buildings,which can improve the seismic bearing capacity and reduce the cost in the mean time,is an effective method to optimize the design.The comparison of structural system selection,structural scheme optimization,the comparison and selection of seismic dissipation technology,and optimization of embedded steel plates in shear walls were carried out for the super high-rise building located in the 9 degree seismic fortification area.The results show that the steel reinforced concrete(SRC)frame-core tube scheme has a higher cost advantage than the steel frame-brace scheme;the frame-core tube scheme can be further optimized through refined design.Based on the SRC frame-core tube scheme,two energy dissipation schemes were applied and compared,the results reveal that the seismic performance of the viscous fluid damper(VFD)scheme is better than the viscous fluid wall(VFW)scheme obviously.Finally,the embedded steel plates in the core tube wall limb in the lower area were optimized by increasing the vertical distributional reinforcement.
