The steel structure consists of steel, beams and columns. The steel structure columns are vertical and horizontal and they are bodies of many buildings in the country today. The most basic material used in the steel structures is steel, which is now one of the most important materials in the construction industry. The most important advantages of steel that make it used in steel framework are high strength, weld-ability, ductility, flexibility, homogeneity and elasticity.
Today, a large number of structures and buildings have used steel structures to provide sufficient strength and resistance against any external pressures and factors. Because the steel structure is made of metal and the most basic used material inside of it is steel. Its flexibility and ductility is less during years and has more Permanence than concrete structures.
The use of steel structures in structures and buildings has made them lighter and more resistant to any impacts, pressures and external factors such as earthquakes. So it can be said that structures that uses steel have more relative equilibrium.
Buildings made of steel structure have a high strength and durability against external pressures and factors because the fixity properties of metals are much higher than those of concrete structures and this makes their variability less and longer. In addition, it is important to know that the light weight of the steel structure always makes the buildings made with this type of structure better than concrete structures. The metal structures are divided into different types depending on the type of connections between them, such as bolt steel structures, welded steel structures, rivets, and so on.
Benefits of Steel Structure
The advantages that the steel structure has over the concrete Structure have led to this, as discussed in previous articles on the advantages of the steel framework over the concrete framework, which is briefly stated below.
Reduce foundation volume
Significantly reduced building weight
increase project progress rate
Possibility of non-destructive inspection and testing at all stages of operation
Raising the level of the underlying building
Ability to correct any defects at any stage without damaging the material
Able to operate in favorable conditions of the factory, resulting in high quality and precision
Steel Consumption in Steel Buildings
In steel buildings, the cost is calculated according to the amount of steel used per square meter of floor area (horizontal image) or cubic meter of building. Cost of steel construction and consumption depends on the following factors:
Number of floors
Load applied to floors
Spans around the column
Structural system (vertical and lateral load transfer system)
