Design and Comparative Analysis of Structure Scheme of Huixin IBC Tall Building /Zhang Xinshan，Lu Yinrong，Yang Qi（China Northwest Building Design Research Institute，Xi"an 710003，China)

Abstract:Optimized design of Huixin IBC building is introduced. The scheme of the building is complicated because there is a big opening through the elevation of the building. The influence of five local structure schemes at key locations of the building on the period, displacement, ratio of stiffness between different stories, and effect of force transmission between components and magnitudes of forces on the components is analyzed. This will help engineers choose reasonable structure schemes on the basis of beneficial conclusions. It will also be a reference for design of complicated multi-storied tall building in high-intensity earthquake region.
