What is Reinforced Concrete Steel? What are the features?

Concrete, which is one of the most used building materials today, can easily meet the pressure forces, while its resistance against tensile forces is almost none. We, engineers, want the material we use in the building to be resistant to both tensile and pressure forces. That is why we place reinforced concrete steel, also known as reinforcement, which is a material with high tensile strength, into the concrete to meet the tensile forces in the tensile region of concrete with very low tensile strength.

Physical and Mechanical Properties of Reinforced Concrete Steel

The changes in the original shape of material under various force effects are called deformation. The deformation property of steel is approximately 15 times more than concrete. For this reason, the deformations after the yield limit in the deforming phase of the steel cannot be followed by the concrete, so cracks begin to form and gradually expand in the concrete. The reinforced concrete element, which has cracks and dents as a result of excessive deformation, may collapse.

The stress value applied to steel loses its linearity as it approaches the yield strength. Even if the force applied to the steel that loses its linearity is reset, the object cannot return to its previous state and undergoes permanent shape change. Therefore, steel is considered to exhibit elastic behavior, except for values ​​where the applied force approaches the yield strength.

Reinforced Steel in Terms of Ductility

The strength of the material depends on the ability of the object to carry without deformation or fracture in the face of a load. While some materials exhibit brittle behavior (brittleness) in the face of the applied load, some materials undergo deformation before breaking and then break. Steel, on the other hand, is a ductile material since it undergoes both elastic and plastic deformation before breaking. Although steel is considered a ductile material, it shows a brittle behavior as the carbon content in its content increases. Therefore, high carbon steel should not be used in earthquake zones and care should be taken to transport high carbon steel without bending during transportation.

The fact that concrete is brittle and steel is a ductile material and that the expansion coefficients of these two materials are close to each other, these two materials can be used together. However, when flat steel reaches its yield point, it becomes difficult to gain ductility, and adherence with concrete is lost. It should be noted that the ribbed reinforcement greatly increases adherence at this point.

Transport and Storage of Reinforced Concrete Steel

Transportation and storage of steel constitute an important place to reduce the losses in the use of steel in the construction site environment.

  • Steels should be transported in different ways depending on the carbon content and thickness to minimize the losses while being transported to the construction site or from one point to another within the construction site. High carbon steels should only be transported as rods without bending because of their brittle behavior, while low carbon steels showing ductile behavior should be transported as coils, hairpins, or rods according to their diameters.
  • Steel, rainwater, sunlight, etc. We must keep it under the covered patio or porch to prevent corrosion by protecting it from the factors.

Classification of Reinforced Concrete Steel Within Itself

According to Manufacturing Types

Steels are divided into 2 according to the way they are rolled. The point to be considered here is that welding should not be performed on steels formed by cold rolling.

  • Cold Rolled
  • Hot Rolled

According to the Carbon Content

  • Low carbon steels: They show ductile behavior. Therefore, the rupture strain is high.
  • High carbon steels: They show brittle behavior. Therefore, the rupture strain is low.

By Yield Strength

  • S220 Class Steel (Smallest yield strength 220 N / mm² steel)
  • S420 Class Steel (Smallest yield strength 420 N / mm² steel)
  • S500 Class Steel (Smallest yield strength 500 N / mm² steel)

According to Surface Shapes

  • Flat Surface Steel
  • Ribbed Steel
  • Knotted Steel
  • Torsion Steel

The formation processes of concrete houses built for life are extremely tiring, laborious, and difficult. The concept of time spreads over very large areas within these houses.

For this reason, the steel house models developed are extremely high quality and time-saving. Constructions started after a certain plan or project is made will continue for days or even months. Thanks to advanced technologies, various models are now produced in steel houses.

The biggest example of this is steel villa houses. These houses are prepared as two-story and easy to install. No additional process is required after the materials used in the production phase are combined. Various answers can be given to the question of whether it is a concrete house or a steel house that people often encounter. This is caused by looking from different directions.

Concrete houses are the species that are constantly known in society and are not odd. However, the steel houses produced today are found odd by people and are not generally seen as living spaces. In developing technology, such structures go to the lives of people.

Why is reinforced concrete house preferred?

Concrete houses, which people have preferred since past societies and continue to prefer, contain a very demanding and difficult formation process. They have a more conspicuous architecture compared to the steel houses, whose construction is constantly increasing today. Both house types have various advantages in themselves. steel house models are both cheap and easy to prepare. In addition, it can be prepared with a few people in terms of workmanship. The planned project can be changed easily and the operation can be undone. However, any change in the concrete houses will result in a great waste of time after various processes. Today, various procedures are completed for each house that continues to be formed. However, home models produced with steel and easily prepared provide many advantages in terms of price, time, and effort. In this case, it meets the needs of people in the best way.

Best home models

Steel houses are made ready for use immediately after a few basic operations. So, why are steel houses, which are more advantageous than concrete houses are less preferred? Steel houses are products that have not been used for a long time and are not preferred because they look simple. Especially the rapid completion of the construction process of steel houses is the simplest example of this. The higher the quality of the structural materials used in the steel house types, the longer it will be. Here are a few details that show that steel houses are more advantageous than concrete houses;

  • It is much easier to build than concrete houses.
  • In terms of cost, it is much lower than reinforced concrete houses.
  • It can be easily prepared and modified.
  • Although it has movable structures, there are many different models available.
  • It is durable and there is no risk of collapse in an earthquake.

A few meters of space is sufficient for these houses, which are prepared by each land. For this reason, it can be easily purchased without the need for plans and projects that have been struggling for days. However, the fact that it is permanent in concrete houses and the costs are constantly increasing are more than suitable for investment, not for use. For this reason, they are frequently preferred in residential areas.

Materials used in steel houses

Steel houses are made with some steel and some insulation material. Decorative processes are applied especially in the houses built.

These houses, which are created with different colors and motifs, are easy to use. Especially windows and glass models provide many advantages. Thanks to its increasing use in living spaces, it provides various benefits to people. In today’s conditions, the uses of concrete houses are quite high. Steel houses are not often preferred, especially for large families.

For this reason, they are generally used in the detached house style. The steel house models, which progress as a developed house style and reveal very pleasant images with their structures, become the preferred points with their two-story and wide types. There are extremely wide possibilities in reinforced concrete house types. In terms of living standards, they are at a much higher level than steel house models. For this reason, it is among the most preferred species today.

Which is more advantageous?

There is a different type of home for every family and individual. With easy installation and affordable price options, steel houses are much more advantageous.

Thanks to the steel companies, which will be completed both effortlessly and without any difficulties, there will be no problems.

In addition, steel houses are much more preferred in families with fewer individuals. In addition, large families can live in reinforced concrete houses in higher standards.

The fact that steel houses are open to long-term use and being portable increases the interest day by day. Looking at, steel houses are seen as much more advantageous. In addition, reinforced concrete houses are designed to be much more useful and offer more possibilities. In today’s conditions, millions of people live in reinforced concrete houses. Due to the design, ease of use, and affordable costs of steel houses, the number of people who prefer steel structures is increasing day by day.
