| Abstract: | A design project of a concrete frame-corewall tall building is presented in this paper. Due to the required inner balconies with 3-story-height at the two opposite corners on some floors, the corresponded edge beams cannot be connected to the two corner columns which are in a diagonal line. The layout affects the lateral stiffness of the structure. The behavior of the structure is compared with the ordinary frame-corewall structure which has continuous exterior frame beams; and in another way, comparison of behaviors of similar structures, in which inner balconies are with different-story-heights, is carried out. It is concluded that the lacking of some corner beams of the introduced structure has little influence on its overall behavior. The influence is only about 3~4%, and the seismic behavior of the structure is quite well. The related section of the Technical Specification for Concrete Structures of Tall Building of China is also discussed in this paper. |
