The amount of steel used plays a vital role in steel structure buildings. Therefore, structural engineers must optimize the structure as much as possible during the design process while ensuring safety, reducing the amount of steel used, and saving costs.
1. Raw material prices
The price of raw materials greatly impacts the cost of building
steel structure buildings, so fluctuations in the price of steel always lead to changes in the overall prices of steel structure buildings.
2. External load
The external load determines the size and strength of a steel structure. If a load is large, the amount of steel used in the construction will increase. In particular, if a structure is subjected to wind or snow loads, both static loads in nature, it should use more steel than other buildings constructed simultaneously.
3. The span of the steel frame
The larger span of the steel frame, the greater the amount of steel used per frame. More than 30 meters is considered a large width. The steel used will increase if the steel frame has a large span and no center pillar.
4. Structure
If a steel structure building has cranes or mezzanine floors, the building will need to meet the relevant requirements of crane security and safe operation. When calculating the design strength for steel columns, columns will be increased in size, and equal cross-sections will be used. This will increase the steel used in the building to support more weight.
