Design for the Television Cultural Centre Hotel is to include a random stack of rooms, inspired by the form of a termite's nest
The 115 000m˛ Television Cultural Centre (TVCC) that will stand adjacent to the China Central Television (CCTV) building is to house a hotel. With 300 rooms it will provide accommodation for visitors to the Chinese broadcasting organisation.
TVCC consists of two towers containing the hotel, and a collection of separate buildings that will house a theatre, digital cinema, exhibition hall, recording studios, and audiovisual rooms. These are covered by a long-span spaceframe roof that wraps up and over the hotel to form a canopy for the whole development.
The architect’s vision for the accommodation is a seemingly random stack of rooms, inspired by the form of a termite’s nest, with a large internal space and balconies on either side.
Designing for such an unusually shaped development in a seismic region with prescriptive codes of practice were a significant challenge for the Arup team.
‘Random’ design
Our solution for the apparently random stack of bedrooms is to arrange frames with cantilevering beams of varying lengths between the rooms. The frames will also form the secondary ductile stability system, solving two design requirements at the same time.

To create the large internal space, the hotel bedrooms will be arranged into two blocks at the front and rear of the building. These will be joined together by the main core housing lifts, stairs and service risers on one side, and the wrapping roof on the other.
Offsetting the core from the centre to provide the internal space resulted in an eccentricity in the stability system at design stage. We resolved this by designing a mega-braced frame on the opposite side of the core which resolved the eccentricity in a spectacular manner.
Seismic challenges
The structural system was then tuned to mitigate the effect of twisting in an earthquake by varying the size of the door openings in the core walls.
The core will provide the main stability for the building under seismic conditions, supported by a secondary system involving ductile frames. These cost-effective solutions will absorb energy in the event of an earthquake.
The next steps
The technical design scheme was reviewed and passed by a panel of experts in the building industry in Beijing. The next stage will be to obtain approval for the construction phase.
