Earthquakes and buildings.
In many countries and areas, it is of great importance to construct buildings which can stand damage from earthquakes. Because most earthquakes are unexpected and unpredictable. Most of the damage we associate with earthquakes first should be human-built structures. We can do little to prevent harms to the individuals insides the building in the event of an earthquake while our advanced technology can provide us with an early warning before the earthquake. So in order to minimize the harms in earthquakes, the buildings have to be able to withstand earthquakes that may occur at any time. For this reason, people all over the world are trying their best to comply mounds of information on the best way to construct buildings that can stand earthquakes.
Two most popular building materials
No doubt that all of us are very familiar with concrete buildings because they can be seen everywhere. But do you know another popular building material? Today, most commercial structures are comprised out of either concrete or metal. These two materials are most popular to construct buildings with different applications because of the numerous advantages. Both materials are extremely strong and durable, ensuring structures built with these materials have a long period of time to use. What’s more, both materials are inorganic, which makes them invulnerable to rot, fungi, termites, and mold. In a word, these two materials do not break down as some other types of materials may. But when it comes to earthquake standing, which materials is better. concrete or metal?
Metal buildings stand earthquake better
Yes, metal buildings have better performance in standing earthquakes. Maybe this answer would be quite surprising to many people. Buildings with better seismic capacity shall be designed to be flexible and move without breaking. The unyielding nature of concrete means that the building may crack and collapse on its foundation if it is hit with a sizable earthquake. However, metal can be formed to flex and bend without breaking to allow the metal building to sway with the movement of the earthquake, thereby reducing the stress on the building and helping the building to remain solid. So nowadays the developers can greatly improve the chances of the buildings standing earthquakes by using metal supports in the buildings.
Several different types of metal used to improve the seismic capacity.
Now we have known that metal buildings stand earthquakes better than concrete ones. But do you know there are also several different types of metal can be used to improve the seismic capacity. The most common type of building material used today is steel or steel rebar. Steel is extremely strong as a building material but also has the ability to flex and stretch far beyond what many individuals would expect. By using steel as supports for the buildings, developers can lessen the chances that the frame of the steel buildings will crack under stress. Although the strength of the earthquake may visibly deform the building, the frame of the building will stand greatly lessening the number of injuries that will occur inside the building as a result of the earthquake.
Another way to construct buildings with better performance in standing earthquakes
With the rapid development of our technology and facilities, many buildings designed to withstand earthquakes today are vastly different from the buildings built by previous generations. Besides using steel in the construction of the buildings, the building now typically have numerous supports located on the first floor of the building. Previously, the first floor of the building was very open while the higher levels had more walls, frames, and supports. But now people have found that during earthquakes, the bottom floor typically collapsed, ruining the rest of the structure. According to this discovery, developers will add more support to the bottom floor in order to lessen the risk that it would collapse damaging the floors above.
Since metal buildings stand earthquake better, if you are in need to construct a building in the future, don’t forget metal building as a good option.
