The Tianjin Science and Technology Museum is located in the Tianjin Youth Activity Center with a building area of 21,000 meters~2 and is designed as a fully cast-in-place frame structure. The building is 144 meters long, 54 meters wide and 45 meters high. It has a ribbed slab, a large column spacing, a large space, and a floor height ranging from 4.74 meters to 7.2 meters. It is divided into 5 zones by function. In the center of the building, a multi-purpose cosmic observation hall with a single-layered grid structure with a diameter of 30 meters is lifted by eight cylinders with a diameter of 0.9 meters. The structure is 6 layers. The 5th and 6th floors are non-standard heterogeneous structural layers. Its scale design is higher than that of Hong Kong and flat to Japan. The 72-meter-span suspension cable prestressed structure is the largest in China, and the single-layer suspension cable stabilizes the cable. The truss form is the first in China.
