Features and specifications of earthquake-resistant properties in Türkiye

We explain the details of earthquake-resistant properties and their most prominent features, and we ensure that their residential and real estate complexes are earthquake-resistant.

What is meant by earthquake-resistant buildings or properties are those buildings whose structural design takes into account elements resistant to earthquakes and earthquakes, depending on the seriousness of the seismic zone and the geographical location of the building.

The most prominent specifications of earthquake-resistant properties are:

  • Its design must maintain its balance from the inside and outside, especially since it is often based on horizontal urban planning in order to achieve this goal.
  • The property’s soil must be selected based on a “soil study report,” which would indicate whether or not it will be suitable for construction and suggest finding solutions to the problems of building on the soil.
  • The type of soil must be compact and exclude fragile and sandy soil, as solid soil clearly contributes to the strength of the building in reducing its shaking during earthquakes.

In this regard, those in charge of the “OmranTRK” company confirmed that their residential projects, including the “Jannat Yalova” project, were chosen to be located on a hill with solid rocky soil.

Earthquake-resistant buildings are characterized by:

  • A cohesive unit that does not disintegrate in earthquakes, and this is due to the strength of the building joints and their ability to absorb seismic pressure, which ultimately leads to alleviating seismic damage and shocks.
  • The earthquake-resistant building is designed according to a system that ensures its support by connecting the walls and ceilings to a stable and solid square, which increases the building’s defence strength against the side effects resulting from the earthquake.
  • In order to maintain the safety of the building, the length of the building is taken into account, so that its height does not exceed 50 metres. If the height exceeds that, the design of earthquake-resistant buildings resorts to placing expansion and subsidence insulators and seismic separators on the upper floors.
  • The loads and self-weights that the floors will bear are calculated with extreme precision, as the task of carrying the roofs is assigned to the concrete columns, which gives the building more resistance to earthquakes.
  • When evaluating the earthquake resistance of existing properties, the principles specified in accordance with the Law on the Transformation of Areas at Risk of Disasters are considered. According to the law, the evaluation process for existing buildings is divided into two parts: buildings up to eight floors and high-rise buildings. The evaluation provides separate evaluation conditions for reinforced concrete and construction processes for each.
  • After the assessment, dangerous structures are identified and the necessary steps are taken, and the necessary permits are granted for demolition work on dangerous buildings.
  • The building, which is at risk from earthquakes, is included in the urban real estate transformation list that aims to renovate and support buildings to make them resistant to earthquake risk.

OmranTRK pointed out a number of factors that are taken into account when designing an earthquake-resistant building, the most important of which are:

Horizontal design of the building

that is, achieving a study of its internal and external stability under the influence of earthquake forces.

Internal stability of the building

that is, achieving sufficient internal resistance of the concrete pieces due to the internal forces of bending moment, shear forces, and vertical forces.

External stability of the building

that is, achieving the balance of the building under the influence of torsional torque and overturning moment, as well as the effect of the change in soil shifting stress.

Vertical design of the structure

meaning the design of the structure to resist the installed loads from the weight of the concrete slab, the columns, and the weight of the floors and walls, to resist the live loads from the weights of the furniture and furnishings and the weights of the users of this building.

One of the conditions for architectural design to resist earthquakes is that the shape of the building in the horizontal plan must be chosen so that it is symmetrical and must avoid angular shapes. In the case of a building with an irregular shape, the building must be divided by making earthquake dividers, since after repeated earthquakes it is forbidden to use triangular or parallelogram plots of land. This is because it constitutes an opportunity for earthquake stresses to be concentrated in the weak parts, as well as for the generation of severe torsional moment stresses in them as a result of the earthquake.

OmranTRK spoke about the properties covered by earthquake insurance, which are:

Residential buildings, which are registered in the land registry as such.

  • Independent properties subject to Floor Ownership Law No. 634.
  • Residential buildings granted by the state as compensation for disasters.
  • Buildings under construction.
  • Buildings that have not yet received a building description and whose type has not been specified in the Land Registry Department, but that meet the conditions of Law No. 6035.

The buildings that are not covered by earthquake insurance in Türkiye are:

  • Separate buildings and sections subject to the Public Housing Law, buildings used for public service.
  • Buildings erected in some rural areas.
  • Buildings violating legal building standards.
  • Buildings built without a clear engineering plan.
  • Abandoned buildings unfit for human use.
  • Independent buildings and departments subject to the Public Housing Law, or those used as public service buildings.
  • Buildings erected in some rural places.
  • Buildings used entirely for commercial or industrial purposes.
  • Buildings constructed without an engineering plan or project.
  • Buildings constructed in violation of relevant legislation.
  • Buildings that are scheduled to be demolished by licensed public institutions.
  • Neglected, dilapidated, or abandoned buildings that are not suitable for residential use.

Earthquake-resistant real estate is considered very desirable for investors, for several reasons, the most important of which is that it gives confidence in everything related to building specifications, guarantees, and earthquake-resistant features, in addition to being characterised by a government guarantee against earthquakes and the highest safe standards.

Cennet Yalova project was built on an area of 10,800 square metres in the Turkish city of Yalova.

“OmranTRK” was keen, starting from the selection of the land, to build the project on a plateau and solid soil, which helps to give full support to the construction.

A soil analysis test is carried out, after which the number of floors allowed to be built on is determined, and this varies from one region to another.

It consists of 9 commercial units and 144 residential units (villas, duplex apartments, regular apartments), with areas ranging from 50 square metres to 311 square metres.

The project was built with the highest engineering standards and modern designs, in addition to indoor and outdoor swimming pools, a gym, Turkish bath, sauna, cafes and restaurants, in addition to 24-hour security guarding.

The project has a wonderful view of the Marmara Sea in the Şınarçek area, and it was built with a special architectural design for this reason, as the project’s apartments enjoy sea views, including the ground floor.
