Steel structure column spacing refers to the distance between two adjacent steel columns, column spacing is more economical practice is set to 6-9 metres, in the large-span structure, column spacing can be appropriately increased, preferably not more than 12 metres. The determination of column spacing in addition to consider the use of the building’s function, production process, structure type, but also need to consider the impact on the overall cost, here we understand how the column spacing affects the project cost.
The cost of steel structure project is mainly affected by steel structure raw materials, construction cycle, etc., while the size of steel structure column spacing directly affects the amount of steel. If a smaller spacing is used, more steel columns are needed to support the structure, thus increasing the consumption of steel and the overall cost. If a larger column spacing is used, the number of steel columns can be reduced, but it is necessary to use larger cross-section size of steel columns, steel beams and other components, which will also increase the amount of steel and the cost; at the same time, a larger column spacing may lead to increased construction difficulty, which extends the construction period, increases the cost of construction and leads to the overall high cost.
The relationship between steel structure column spacing and project cost is not only simple, it must be under the premise of ensuring the safety and stability of the structure, by comparing the amount of steel used under different column spacing, construction cycle, etc., choose a more appropriate design of column spacing, so as to realise the effective control of the cost.
