Designing Tall in a High Seismic Zone
The Chengdu Dongcun Greenland Tower boasts a complicated sloping geometric design to symbolize the surrounding snowy mountains. To accomplish this distinctive architectural vision, the main tower employs a core wall with sloping walls, the first use of this structural system in a high-rise building in China.
We are providing structural design services to Adrian Smith + Gordon Gill Architecture for the structure’s design which, upon completion in 2021, will be the tallest building in Southwest China, at 468 meters.
- Surrounding the main tower are two smaller towers, respectively 167 and 174 meters, and a six-story podium.
- The main lateral force resisting system is a steel reinforced concrete core wall with sixteen steel reinforced concrete columns that zig-zag along the height of the tower following the architectural design surface.
- The second lateral force resisting system is a high-performance brace-frame system of steel-reinforced concrete columns with an outer periphery of steel beams and braces.
- The braces are located on the edges of the surface facets, serving as both the structural members and architectural components.
- The final product is a highly integrated and efficient structural system for a super tall building in an active seismic zone.
