“Short Column Behavior” That Makes Buildings Risky in an Earthquake

In order not to lose our citizens due to negligence, we should be conscious as a people. Therefore, we need to know the factors that cause a building to collapse in an earthquake. One of these elements is ‘Short Colon Behavior’It’s called an event.

But in order to explain the Short Column Behavior, first a little bit of how the columns work and why because they are vital We should talk.

Columns form the foundation of a building. Therefore, it is the most important issue.

Columns are basically vertical structures that transmit compressive loads. Columns on the ground floor of a building, large enough to bear the weight of the upper floorsenough to distribute the loads from the slabs and beams to the foundations and the soil below. must be durable.

Columns should be positioned equally (in the same location) on all floors for the most efficient support, and civil engineers should measure the maximum weight that can be supported by the column before choosing an appropriate design. In modern construction, steel and concrete materials are used for the column. The load on the columns is too high in multi-storey buildings composite columns composed of both steel and concrete should be used.

Only concrete and iron materials can be used in low-rise (maximum 5 floors) buildings.

Up to 5 times In low-rise buildings, the columns carrying the load do not need to contain steel. If properly constructed, concrete columns become earthquake resistant. Then, how should the concrete columns in the apartments in which most of us live be built? According to the earthquake regulation, at least 6 14’s or at least 4 16’s in the building column serrated and zero iron must be used.

So how long should the columns be? Why is the behavior of short columns deadly?

If we have talked enough about how important the columns are in building construction, we have come to our main topic. Durability of concrete columns containing iron, varies according to their length. It has been learned from past earthquakes and experiments that the short columns of reinforced concrete carcass buildings with columns of different heights on one floor are stronger than long columns. much more damaged.

Short columns absorb less and cannot withstand the force of earthquake shaking. The reason he can’t stand is because it’s short The reason is that it was not decorated with durable enough material.

The stiffness of a column means resistance to deformation, i.e. the greater the stiffness, the more to deform it. the greater the force required. A short column can be significantly damaged during an earthquake if it is not adequately designed for such a large force. to this behavior Short Column Behavior is called.

We hardly ever see buildings built on short columns anyway. Short columns are used in mezzanine floors. Therefore, the most dangerous place to be in an earthquake, They are mezzanine floors supported by short columns (!). You can watch the Short Column Behavior in the GIF above.

As you can see, even these short non-bearing columns become what happens in an earthquake. With research that takes only a few hours, we can learn and learn this information. ‘Then this is how it should be done‘ if we can say, Why don’t the people who build these buildings insist on building them the way they should be?
