Core Testing and Earthquake Resistance Test

Building Strength and Earthquake Resistance Tests: Core and Earthquake Resilience Test

In today's world, earthquake resilience tests are of great importance, especially for those living in regions prone to earthquakes. In this blog post, Quray Group will focus on two essential tests for evaluating the strength and earthquake resistance of buildings: the "core test" and the "earthquake resilience test."

What is a Core Test? A core test is a compression test conducted on the strength of the concrete used in buildings. This test evaluates the reaction of concrete under pressure and other characteristics, providing an overall assessment of a building's resilience. The core test can be applied by obtaining samples of different diameters using tips on the core machine. By taking samples from various points of the building, an overall evaluation of its earthquake resistance can be made. Core tests can be applied to buildings with completed frame structures or all reinforced concrete buildings, regardless of their age, providing an additional safety measure for residents.

How is a Core Test Conducted? A core test is conducted by using specialized core machines to obtain samples from designated points. The process generally involves the following steps:

Preparation Stage: A specialized team determines and marks the points where core samples will be taken. Safety measures are taken to prevent dust and debris during sample collection.
Drilling Process: Drilling is performed to obtain cylindrical samples using a core machine. Cooling is applied during the drilling process to prevent the sample's structure from overheating.
Sample Collection: The cylindrical concrete sample, known as a core sample, is carefully extracted from the core machine, ensuring the integrity of the sample for a healthy test. The core sample is labeled, and necessary information is recorded on the sample.
Laboratory Stage: Core samples undergo various tests in a laboratory setting. These tests include compressive strength, freezing-thawing point, chemical composition of concrete, and other relevant properties.
Preparation of Core Report: The results of the tests conducted in the laboratory are analyzed by experts, and a core report is prepared, indicating the building's earthquake resistance status.

Does a Core Test Harm the Building? When conducted correctly, a core test does not harm the building. The holes created during the application are filled with a special mortar, ensuring no risk to the building. Those considering this test should ensure that it is performed by qualified professionals using appropriate equipment.

Why is a Core Test Conducted? The core test is generally performed to determine the earthquake resistance of buildings. Additionally, it can be used for the following purposes:

Determining the concrete quality and properties of the building.
Identifying existing concrete properties in buildings where reinforcement is planned.
Determining the cause of damage in damaged buildings.
Assessing the capacity of structural systems in buildings undergoing renovations.

How Much Does a Core Test Cost? Core test prices may vary according to the pricing policies of authorized private institutions. For core test prices in Antalya, you can contact authorized companies. Additionally, for a free core test, you can apply to the District Governorship, Municipality, and the Ministry of Environment, Urbanization, and Climate Change.

Earthquake Resilience Test (Building Strength Test): What is it? An earthquake resilience test, also known as a building strength test, involves a series of inspections and analyses to determine how resistant a building is to earthquakes. This test helps assess how the building will respond to the load it will be exposed to during an earthquake. The earthquake resilience test is not only applicable to older buildings or those in earthquake-prone areas but is also crucial for ensuring the safety of life and property in new buildings.

How is an Earthquake Resilience Test Conducted? An earthquake resilience test involves multiple tests and analyses using different methods and techniques. It is generally conducted as follows:

Visual Inspection of the Building: A visual inspection of the building's columns, beams, walls, and other elements is conducted to check for any damage.
Conducting a Soil Study: Selecting the right soil is as important as the structural features of the building. A soil study determines the soil's properties and bearing capacity, evaluating whether the building is constructed with suitable features for the soil.
Identification of Structural Flaws: A structural assessment of the building is conducted to identify any conditions that may pose a risk.
Taking Core Samples: Samples are taken from the building's load-bearing elements, such as columns and walls, using a core machine. The properties and load-carrying capacities of cylindrical concrete core samples are evaluated.
Building X-ray: Using special devices, the iron properties, wear condition, and adequacy of the columns and beams in the building are assessed.

Building earthquake resilience tests provide a comprehensive understanding of the risk situation of all elements from the building's foundation to its roof. These tests are conducted without causing any harm to the building and are analyzed by authorized experts, resulting in an earthquake resilience report.

Who Conducts the Building's Earthquake Resilience Test? Where Should You Apply? The earthquake resilience test can be conducted by municipalities, Provincial Directorates of Environment, Urbanization and Climate Change, District Governorships, and authorized private companies. Those interested in conducting this test should contact a reliable institution or company providing these services.

How Much is the Price for an Earthquake Resilience Test? Earthquake resilience tests are conducted by private institutions approved by the Provincial Directorate of Environment, Urbanization and Climate Change for a certain fee. Prices may vary depending on the building's features, the number of floors, block count, floor area on the ground, and the pricing policies of companies in the city. Additionally, the pricing for earthquake resilience tests may differ for informational purposes, urban transformation, and official requests from institutions. Those considering the test in Antalya can contact companies conducting earthquake resilience tests to inquire about prices.

Quray Group, in all construction projects in Antalya, aims to adhere to all tests during both the construction and post-construction phases to create a safe living space.
