The build ability of the nodes was an important challenge while designing the 610meter tall Guangzhou TV and Sightseeing tower.
Although none of the 1100 steel nodes are identical, still we succeeded in creating one single type of node.
The structure consist of a open lattice-structure that is twisted over it's axis, therefore creating a tightening waist halfway up the building. This twist has created a slender grace-full profile.
The design of the lattice-grid is not only a structural one but is also driven by esthetic and architectural and environmental considerations.
The rings are placed on the far inside of the columns so that they spatially miss each other and are connected off-center. This will make that the inside view is dominated by the rings, while the view from the outside is dominated by the sloping columns.
All rings are placed under an angle of 15 degrees, so that both an opening is created for the entrance at the base of the tower, as well as that a sloping deck is created at the top of the building, offering magnificent views over the city.
