Shanghai Science and Technology Land (SSTL) is a cultural center for exhibiting the development, history and research of natural science and technology from around the world. It is also an education center open to the public.

The SSTL consists of a main building, auxiliary buildings and a sunken square. It covers a site area of
68 000 m² and has a total of 96 000 m² of building area. The four floor main building is designed in a semi-circular plan.

The building's structure is constructed with a prestressed space frame system. A single-layer latticed dome structure was selected for the center hall in accordance with the function and shape of the building. Pipe sections are used in the steel dome with a drum-type joint system and I-section members are used in the aluminum dome with a plate-type joint system. In order to ensure the safety and rational of the structural design, theoretical and experimental
studies were made to solve key problems in the design process.
