Abstract：
Some Beijing century commercial center has a large pattern change above second floor.Columns following first floor is a rectangular network, the upper is two curved structure. so designning a 800 mm transferring slab in the first floor(about 6000 m2). The project is in 8 degrees security region, having these innovations as below: the 800 mm transferring slab is the thinnest in 8 degrees security region (others’ thickness are usually much more than 800 mm); it strives to make up-down structural stiffness uniform, avoiding a quality volume with large stiffness appearａnce at the thick transferring slab. This paper trys to research and explore in the structure of transferring slab。
