In order not to lose our citizens through negligence, we as a people must be aware. Therefore, we need to know the factors that cause a building to collapse in an earthquake. One of these elements is ‘short colon’It’s called an event.

But to explain the behavior of short columns, first a little bit about how the columns work and why because they are vital We have to talk.

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

Columns are basically vertical structures that transfer compressive loads. Columns on the ground floor of a building, large enough to support the weight of the upper floorssufficient to distribute the loads from the slabs and beams to the foundation and the ground below. must be sustainable.

Columns should be placed evenly (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 selecting a suitable 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.

In low-rise buildings (maximum 5 floors) only concrete and iron materials may be used.

Up to 5 times In low-rise buildings, the columns that carry the load need not contain any steel. When properly constructed, concrete columns become earthquake resistant. How then should the concrete columns be built in the apartments in which most of us live? Minimum 6 14’s or minimum 4 16’s in the building column according to earthquake regulation serrated and zero iron must be used.

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

Having talked enough about how important the columns are in building construction, we have come to our main topic. Durability of concrete columns with iron, varies according to their length. It has been learned from previous 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 earthquakes. 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 sufficiently designed for such a large force. to this behaviour Behavior of short columns is called.

We almost never see buildings on short columns anyway. Short columns are used in mezzanines. That’s why the most dangerous place to be in an earthquake is, They are mezzanines supported by short columns (!). You can watch the short column behavior in the GIF above.

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