Greenland Group Suzhou Center

The 358m tall Greenland Group Suzhou Center tower is currently under construction in Wujiang, China. The mixed-use building program consists of office floors in the lower levels and a hotel above. The lower level office floor plan is barrel-shaped, while the hotel floor plan consists of two curved single-loaded hotel bars facing north and south. Differences in the optimal architectural lease depth and core size for these two different programs are addressed by eroding the middle third of the core in the hotel portions of the building. This forms an atrium which extends clear through the building from east to west façade, giving the tower its signature ‘eye of the needle’ form.  While adding an important architectural element and providing dramatic views out to the east and west, the atrium in this configuration resulted in the core being split in two, greatly reducing its structural stiffness. To address this, the two isolated building cores in the upper hotel floors are laced together using structural steel bracing to form a composite ‘coupled core’. The behavior of this unique ‘coupled-core’ structural solution under lateral and torsional loads and the analysis and detailing of the composite lacing connections will be discussed. 

Attendees will earn 1.0 hour of Continuing Education Credit. CE certificates will be emailed after the event.

Please register by Friday, February 2 to guarantee your place.  Registrations received after that time will be honored if possible, but cannot be guaranteed.
