How to Build and Maintain Earthquake Proof Buildings - A Topic for PE Review Course
An Earthquake is one of the natural disasters that occur in the world. After an earthquake, buildings collapse, the roads are damaged, and deaths happen. Some regions in the world are more earthquake prone than the others. For example, Japan is a very earthquake prone country.
As in other situations, prevention is better than cure. We may not be able to prevent an earthquake from happening. But, we can always build buildings and systems that are earthquake resistant. So, let us look at some methods by which we can build earthquake proof buildings.
When an earthquake occurs, different types of shock waves travel across the buildings. The shock waves can flow in vertical direction, circular motion, or horizontal direction. But the maximum devastation is caused by waves that travel in horizontal direction. You must keep this fact in mind while designing earthquake proof buildings. Taking PE Review will give you good guidelines on earthquake protection.
One method is to have a light roof. A combination of insulation and steel cladding can be used for a light roof. The floors also have to be made as light as possible. The floors must be able to bend under an impact and not collapse.
The foundations of the building must also be laid out carefully. Easily twistable springs and cylinders with cushions must be used for the foundation. The core of the cushion is made of lead. And the lead is surrounded by one layer of rubber followed by another layer of steel and so on. During an earthquake the springs and cushions move along with the forces and shake of the earthquake, and so the building is not damaged.
You need to build a building with a lot of energy absorbing materials. The materials must be very ductile. Examples of materials with low ductility are concrete and brick. So you should reduce the amount of concrete and brick while building earthquake resistant buildings. Instead, steel with good provisions is more suitable as an energy absorbing building material. So contrary to popular building, a light-weight building is more sustainable than a solid building. The PE Review Course covers all types of protection against earthquakes.
Damping is another mechanism used by engineers. Viscous dampers are connected to some heavy material that is mounted on top of the buildings. These dampers are able to absorb the shocks. The mass material move in a direction opposite to that of the shock and so protects the building. The PE Exam includes the topic of building homes that are earthquake proof.
But, what is the extent of protection you will give to a building. Say, a location has earthquakes of various intensities. When you build a new building, you should design it to withstand an earthquake with the highest intensity at that place. You can only maximize the protection, but you cannot avoid minor destructions to the building. Computer simulations are also used to arrive at the optimum structure of a building.
In the US, the engineers refer to National Seismic Hazard Maps before building a site. The International Building Code is also a constant guide. So, there are different methods and guidelines to build earthquake proof buildings. The PE Exam Review deals with all types of earthquake protection.
