The issue of earthquake-resistant houses is of great importance for our country, which is located in the earthquake zone and has witnessed the devastation caused by earthquakes of 7.7 to 7.6 magnitude in the past, affecting 10 provinces, especially Gölcük, Van, Erzincan, Elazığ, İzmir and recently Kahramanmaraş. Such a serious risk is one of the main factors that should be taken into consideration both for the people who will reside and for construction companies in terms of focusing on durable structures. So, what should be the basic features of earthquake-resistant buildings? Let's examine them together.

The quality of prefabricated products is determined by both design and production. The design of a bespoke prefabricated structure is done by the architect. However, there is often a compromise between design and manufacturing. Perfect coordination of the design and production teams is required. On site, experience and supervision determine the quality of production.

Prefabricated Building System is more durable than traditional building systems. Because...

Galvanized steel profiles form the carrier system in prefabricated buildings. The manufacturing project, which is drawn specifically for each project, is designed by engineers by making heat and static calculations; It is designed with programs specially produced for this sector. At this stage, the structure of the material used and the joint system are of great importance.

As Prekon Prefabrik, "fibercement board", which is the main material we use in the wall panels of the prefabricated buildings we produce, is produced from silica sand, cement and cellulose and is a higher quality coating material than betopan. Fibercement, which has A1 class fireproof feature, has a high density as it is produced by pressing process and this density increases the strength. In addition to these, fibercement, which has features such as minimum thermal expansion and water repellency, is produced to provide the highest performance on exterior facades. Although the material is a cement-based material, it does not disperse like concrete. In this way, in the event of an earthquake, it does not turn into an element that threatens human life as it does not disintegrate and turn into rubble, on the contrary, the non-disintegration of the panel; Even if the building collapses in a severe earthquake, it ensures the formation of a life triangle and reduces the risk of damage to people.

The use of the prefabrication construction technique, as opposed to on-site construction, speeds up and facilitates the assembly process in the construction industry, thanks to the principle of "more factory (pre-production) and less on-site work".

The fact that prefabricated buildings are not built with multiple floors and are built with horizontal architecture is one of the advantages that makes them more resistant to earthquakes. Prefabrication, which is a lighter system and does not create heavy excavation, is a building technology that is pre-produced and produced in a short time. In this system, wall panels are arranged between light steel profiles according to a certain axis system. Column and beam placement is also a system that must be applied in every building. Balance is provided with omega profiles and u sheet profiles according to panel placements. In order to have a rigid (balanced) structure, a solid structure is obtained by using fasteners in x/y/z direction. Trusses and purlins made of wood on the roof of reinforced concrete structures are manufactured from steel material by making the same static calculations in prefabricated structures. The insulation material and roofing material placed between them can be applied according to the employer's demand. These materials will not have much effect on durability.

Flexibility of Prefabricated Structures

Since prefabricated structures do not have a joint as in reinforced concrete, their flexibility will provide advantages in issues such as thermal expansion and earthquakes. The same system is used in bridge piers. The reason for making dilatation joints to reduce the rigid structure of reinforced concrete structures is the same: In long and large span structures, gaps are left at certain intervals from the foundation to the roof of the building so that the structure can behave flexibly in any pressure. This flexibility is inherent in prefabricated building technology and there is no need for a dilatation joint. This flexibility of the structure reduces the possibility of the building collapsing in an earthquake and provides an advantage.

Earthquakes are natural disasters that strike the earth at different distances and can occur at different intensities. Therefore, the damaging and destructive effect of each earthquake is not the same. In addition to this, we now know that not only the intensity of the earthquake but also the quality of the structures is one of the most determining factors in earthquake damage. Prefabricated buildings are a very advantageous alternative in earthquake zones with their durability, flexibility and lightness. Thanks to the quality of the materials used, high durability is ensured against unpredictable and unpreventable natural disasters such as earthquakes and adverse weather conditions. Additional advantages of prefabricated buildings are that they are more economical, fast in production and modular and can be disassembled and transported when necessary.
