One of the most important factors of a durable structure is to maintain its state of balance against the loads on it. The concept of rigidity, which comes into play at this point, ensures that the building remains intact thanks to the physical resistance it provides. Well, what is the rigidity, which is one of the most important factors to be considered in the construction process? In this content, which we prepared as Enhar Yapı, one of the pioneers of the prefabricated building sector, we will answer all the questions you need to know about this concept, which is one of the most basic elements of construction, while answering questions such as what rigidity means, what happens if the rigidity increases, how to make prefabricated building statics.
What is Rigidity?
Rigidity, which has its origin in English, has passed into our language from the word rigidity, which means unchanging in the face of rigidity. This concept, which is the most basic element of a solid structure, ensures that the structures remain stable against the loads they have and may have, and that they do not experience any form loss. Rigidity, which means hardness, ensures that the structures can respond to the stiffness they encounter in the face of situations such as loads and earthquakes without breaking their structure, and that the balance that the structure must show in order to survive is maintained. In this way, buildings show ideal flexibility in the face of heavy loads without deterioration in their structures. It is a well-known fact that buildings should show flexibility in situations that shake the foundation of the building, such as an earthquake. However, this flexibility should not distort the shape of the building due to the load encountered. The rigidity that comes into play at this point enables the structure to work in coordination with this flexibility, making it possible to maintain its shape. We answered the question of what is rigidity. Let’s now answer the questions of what is the center of stiffness, how to calculate the center of stiffness.
What is Center of Rigidity?

The center of rigidity can also be expressed as the center of gravity of the columns, that is, the vertical bearing elements. In this way, the columns that carry the general load of the building against the pressure maintain their stiffness and shape, and ensure the preservation of the structure of the building.
How to Calculate Center of Rigidity?

Soil survey, which is one of the most basic elements of the building concept, and the calculation of the center of rigidity, such as excavation, are also the points that should be known and the most important points in the building construction process. The steps to be considered and implemented while calculating the center of stiffness are as follows:
● First of all, the first step is to calculate the inertia of the columns and walls of the building.
● Afterwards, a reference point must be selected separately on the x and y axis.
● The distance from the center of gravity of the walls and columns to the reference point should be calculated, and the distance to this point should be multiplied by the moments of inertia.
● The obtained value should be divided by the moment of inertia of the whole structure system and as a result of this process, the center of rigidity of the structure is obtained.
● To express it as a formula, the center of stiffness calculation is found as [ Curtain(b*h³ / 12)*X₁ + Column(b*h³ / 12)*X₂ ] / [ ∑b*h³/12 ].
Now that we have answered all the curious questions about rigidity, let’s move on to answering the question of how to make prefabricated building statics.
How is Prefabricated Building Static Made?
Measuring engineers[/caption] Prefabricated structures, which have become very popular in recent years with their fast installation, options suitable for every budget and their desired design, offer a very ideal living opportunity with the comfort they provide. Thanks to the prefabricated houses, which can be owned in 1-2 weeks on average, you can design your living spaces as you wish and find peace quite easily. Building statics is one of the most important points to be considered for prefabricated buildings, as it is for every building. So what is building statics? Structural statics is the dimensioning of the systems of buildings in a safe and sufficiently rigid manner. The most important factors when calculating building statics are external and internal factors. By calculating the strength of the columns and the reaction of the building against natural disasters such as earthquakes, any problems in the shape and reliability of the structure can be prevented by preserving the strength and rigidity of the structure against such stresses. Prefabricated buildings gain reliability very easily and quickly thanks to their simple structural statics compared to reinforced concrete buildings. In this way, the fact that they are not affected by internal and external factors encountered for many years makes prefabricated structures very safe as well as being practical and comfortable.
