The CCTV building is one of the several big Beijing Olympic projects, which houses the headquarters for the Chinese Central Television Network. Its design shows unique style, but great structural engineering challenges to overcome. The following presentation provides an overview of how these challenges were overcome. (Presented at Monash University, Department of Civil Engineering, August 2008).
115. Piled Raft is 7m thick and has a footprint greater than the towers
116.
117. Link up external columns with internal steel core via pin-joints
118. Trusses span the bottom two floors of the overhang, loads above are transferred to these trusses, which subsequently transfer loads to the diagrid system
129. Tests also show that some braces go into plastic buckling during the Earthquake Dissipate seismic energy (GOOD)Maximum downward displacement = 700mm
Towers constructed at opposite diagonal corners of a 160m x 160m footprint, linked by an L-shaped podiumCo-joined at the top by an L-shaped bridge opposite the podiumTower footprints are 40mx60m and 52mx42mThin concrete cores support internal floors

This is the current typology of a skyscraper, there’s a core and a group of people here and people there and you see each of them isolated, there you can do two things: Combine all cores to make the communities into one or distribute the cores without dividing the communities
