What are earthquake resistant buildings?
All buildings that are constructed are classified according to special criteria to absorb the waves sent by earthquakes and tremors so that the building is not affected by them or subject to cracking or demolishing under the name of earthquake resistant buildings.
It is known that earthquakes create rapid waves in all directions while traditional buildings are designed to resist vertical forces affecting them. Earthquake resistant buildings are constructed according to a structural system that allows them to resist horizontal forces that arise as a result of earthquakes and earthquakes.
Why are earthquake resistant buildings constructed in Turkey?
The main objective of constructing earthquake resistant buildings in Turkey is to make urban structures sufficiently fortified to avoid damages that may be caused by earthquakes, and to withstand potential seismic activity so that the building is not damaged or loses its function, and thus reduces the loss of life thanks to the failure of resistant buildings to collapse For earthquakes.
The Turkish government has set special standards for the construction of buildings in the context of combating the destruction caused by earthquakes, especially in the areas most prone to recurring earthquakes. These standards were manifested in building strong and solid facilities according to a special construction system so that they withstand the largest earthquake that can occur.
How are earthquake resistant buildings constructed in Turkey?
When an earthquake occurs, a horizontal load is formed that causes the walls and beams that connect them to vibrate, and the upper and lower parts of the building move in opposite directions, causing severe stress that causes the supporting structure to crack and the building to collapse.
The strategy for constructing earthquake resistant buildings lies in confronting the earthquake forces that release waves that push the building from one direction, and counteracting them is by pushing the building in the opposite direction, through several methods, including:
1. Insulation base:
This method includes constructing the building on a flexible foundation, so that the foundation of the building rises above the ground on flexible cushions consisting of springs, cylinders and metal balls, which absorb shocks, making the building separate from the source of vibration.
2. Building Structure Support against Earthquake Resistant Buildings:
The structure of the building can be made strong and resistant to collapse by redistributing the forces transmitted through it during the earthquake, and one of the most important elements of strengthening the structures of earthquake resistant buildings are shear walls, which is one of the techniques that help transfer earthquake forces to the foundation, in addition to the cross arches that are often made Reinforcement of shear walls, which are steel beams that have the ability to counteract pressure and push seismic forces toward the foundation.
The foundations of the building must also be taken care of and linked well to the ground, avoiding building on unstable soil and choosing cohesive soil for construction, to reduce the risk of building vibration in the event of earthquakes.
3. Pay attention to the dimensions of the building:
Specific rules for determining the dimensions should be adhered to, so that the height of the building does not exceed 50 meters, and if it is more high, it must be divided by expansion joints and seismic joints, and attention must be paid to the ratio of the height of the building in relation to its width so that the building is more susceptible to collapse whenever its width is small in relation to its height.
What are the advantages of earthquake-resistant buildings in Turkey?
Earthquakes can occur anywhere on the face of the earth at any time, and it is known to cause great damage and loss of property and lives. When you choose to live in an earthquake-resistant building, you choose safety from potential earthquake risks, since earthquake resistant buildings have It has many advantages that are not available in other buildings, which are:
1. Hardness and strength:
The construction of traditional buildings is based on the vertical support of the building so that it is resistant to the forces of load, tensile and pressure, but in the event of earthquakes, it sends waves in all directions, and in the absence of horizontal forces that address the earthquake, the building is at risk of collapse, especially if it is not built In the right way, as for earthquake resistant buildings, the construction technology focuses on making the building strong and rigid in an exaggerated manner so that it supports itself and counteracts the tremors caused by earthquakes and saves lives.

2. Stable foundation:
The stable foundation is the most important and basic factor when constructing any building, regardless of possible natural disasters. Earthquakes and tremors, if they are repeated, can affect the foundations of the building in the long run, which may cause its collapse. In the case of earthquake-resistant construction, it is based on foundations. Flexible works to absorb shock waves caused by tremors and earthquakes and keep the building away from vibration, which maintains sound and stable foundations that support the building.
Earthquake resistant buildings have a regular distribution of forces that pass through their structures during a vibration, so that the building moves evenly, which works to absorb and dampen the shock without harming the building, but if the building is irregular, the force will be concentrated on one side of the building without The other, what causes the collapse when the building is shaken.
The standards for the construction of earthquake resistant buildings depend on the adoption of multiple shock-resistance strategies, one of which works in case the other fails, this is likely to affect the high cost of the building, but its value will appear when an earthquake occurs as one of the most important safety and security standards.
