It’s not just rotten buildings that collapse during major earthquakes. Sometimes a solid building can be damaged or even destroyed by the building next to it hitting it. This is called the “hammering effect”.
Turkey is a country of earthquakes and how painful consequences this situation can cause. Kahramanmaraş-centered earthquakes we saw it once again. The 7.7 and 7.6 earthquakes caused great destruction in at least 11 provinces, especially in Kahramanmaraş. According to the data of the Ministry of Environment, Urbanization and Climate Change, the cost of the 6 February earthquakes, More than 100 thousand buildings it happened.
The fact that more than 100 thousand buildings have been demolished or an emergency demolition decision has been made means that all of these buildings are rotten. not coming. In fact, some buildings unfortunately collapsed due to the buildings next to them. In fact, many of you have watched; This was the reason why very strong rumbles broke out in some buildings that were shot at the time of the earthquake. Buildings colliding with each other”hammering effect“It greatly increased the intensity of the earthquake.
So what is this hammering effect? How did it increase the balance sheet of the earthquake?
Both in Turkey and in other countries row houses is common. You know some streets; There are dozens of houses built on a row. These buildings sometimes have the same elevation, and sometimes they are at different heights. This is what we call the “hammering effect”, exactly. between these buildings is happening.
Severe earthquakes cause tall buildings to shake. This is very it’s a normal thing. However, sometimes buildings start to collide with each other with the effect of earthquakes. Sometimes buildings with the same elevation and sometimes buildings with different heights are affected by earthquakes. bump into each other. This phenomenon is known as the hammering effect.
One of the best examples of the hammering effect during an earthquake:
The hammering effect of two independent buildings adjacently lived because it was built. Let’s take a simple example: If the buildings above were built on a single floor, they would sway as a whole. However, with two different foundations, which are adjacent to each other, independent columnshas led to this situation.
The greater the difference in height, the greater the damage from hammering!
The extra damage caused by the hammering effect in the event of an earthquake depends on many variables. In this context, two buildings with the same elevation are connected to each other. it will crash through the roof. However, this situation changes as the height difference increases. The higher building receives damage from the place it hits the lower building. can’t stand. In such a case, destruction would be inevitable.
It should not be forgotten that; building during a strong earthquake. in which direction It’s hard to know when it will swing. A building that is destroyed in the middle floors due to the hammering effect can also collapse on the surrounding buildings. Here is the extent of the damage will increase several times.
The hammering effect can be absorbed very easily.
The risks caused by the hammering effect can be eliminated very easily. The first precaution that can be applied is between buildings. is to put enough distance. In this way, buildings can be prevented from colliding with each other. If this cannot be done, the gap between earthquake joint applications and buildings. seismic isolation can be achieved. In this way, the effects of large earthquakes can be reduced to some extent.
