The term “steel framework” is widely heard in construction, and nowadays, it forms the primary structure of most buildings. The components of a steel framework are steel structures that, in the form of beams and columns, create these frameworks and contribute to the stability of the building. Saman Dez Pars Company has addressed the advantages, disadvantages, and provided information about steel frameworks and steel structures by preparing this article. Stay with us.
What is a Steel Framework?
Steel structures are produced and prepared in factories; therefore, this contributes to speeding up their implementation. The faster implementation of steel frameworks compared to concrete structures reduces construction costs. Additionally, consistent quality control in factories reduces material wastage.
Due to the greater stability of properties in metals, steel structures or steel frameworks have higher strength and resistance compared to concrete and demonstrate greater resistance to external factors and pressures. Additionally, the lighter weight of steel frameworks allows for better balance compared to concrete structures.
Why Use Steel Structures?
This is the question that most readers’ minds are drawn to, but the answer can be provided by mentioning the following reasons. In the continuation of the article, we will explain each of the advantages of steel frameworks.
Saman Dez Pars Company is a construction company in Tehran that also produces and uses steel structures in construction projects.
Cost Reduction
The structure of the building determines construction costs. Steel structures are cheaper and more cost-effective than concrete structures.
Creativity in Design and Construction
Steel structures allow designers to soar creatively and bring creativity to execution. By using steel structures, natural light can be utilized in buildings.
Cost and Time Management
Metal structures are fabricated by skilled individuals in factories. Therefore, this increases safety and confidence in the process of constructing steel structures. According to industrial surveys, the use of steel structures has resulted in better cost and time control in construction.
The uniformity of metal properties reduces the impact of external factors and provides greater strength to the structure. This leads to savings in material consumption.
Longer Lifespan
Steel structures have good resistance against natural elements such as strong winds, storms, harsh weather conditions, heavy snowfall, and earthquakes. Additionally, resistance to corrosion has made this type of structure popular.
High Resistance
The resistance of steel structures is higher compared to concrete structures. For this reason, steel structures are used in building spans and large halls. Additionally, in unstable ground conditions, this type of structure is highly popular and increases structural resistance.
Advantages of Steel Structures
If you want to become familiar with the advantages of steel structures, pay attention to the continuation of the article.
Steel structures have the following advantages:
* High resistance and strength against compression and tension
* Possibility of quality control of steel during production
* Possibility of structure development
* Possibility of prefabricating components before installation
* Faster installation and implementation of steel structures
* Possibility of using steel structures at high elevations from the ground surface
* Less space occupation by steel frameworks
* High resistance against earthquakes and natural disasters
* Stability and durability in steel
* Less waste during the use of steel structures compared to other materials
* Possibility of reusing steel
* Flexibility of steel shaping
* Prevention of vibration and stress concentration
* Prevention of building damage
Disadvantages of Steel Structures
In the previous section of the article, we talked about the advantages of steel structures, but steel frameworks are not without flaws, and it is better to identify their disadvantages as well.
The disadvantages of steel structures are as follows:
* Lack of resistance at high temperatures
* Corrosion and degradation due to external factors
* Tendency of pressure elements and parts to buckle
* Inappropriate welding
Connections between steel components in buildings are made with rivets, screws, nuts, and bolts, and welding. The use of screws and bolts and the production of steel frameworks are cost-effective methods. However, for various reasons, this method is less used in our country. Therefore, welding connections are more prevalent.
However, due to the lack of sufficient skills in some Iranian welders, the use of old tools and machinery, lack of thorough examination by supervising engineers, high costs of weld testing, and some other reasons, welded connections have weaknesses.
