Which is cheaper, steel structure or frame structure, to build a 1000 square meter hotel?

The key depends on the design scheme, such as the height and number of floors you require and the span of the room.

At present, there are three feasible structural forms:

1. Cast-in-place reinforced concrete structure

2. Steel structure

3. Integral assembly of long-span prestressed concrete floor slab

Overall, the third scheme is low in cost: it has the characteristics of large span, fast construction, high bearing capacity and high fire resistance rating, but it can only be limited to buildings below 28 meters, and the installation above 28 meters is more difficult and the cost increases more.

The specifications of long-span prestressed concrete floors are 9m,12m,15m,18m, 2 1 m and 24m. The bearing capacity is 7.03~25.67kN/ m2. That is, it can bear 700 kilograms to 2.56 tons per square meter. The completed hotels can be spaced at will as needed.
