To modify buildings so that they can withstand seismic activities, seismic retrofitting is usually done. There are several techniques that are usually used. The main aim is to make electives more resistant to ground motions and soil failure. Therefore, in case of harsh climatic conditions that may cause motions, the buildings will be safe from damage. There are so many Earthquake Retrofit companies that are coming up. This is because of the high demand especially in areas that are more prone to earth activities. The following are some of the common techniques.
To begin with, the first PRESS approved technique is called external post-tensioning. This is a method that has been applied for many decades since its approval. In case you are wondering, PRESS is research body that has been there for decades, and it operates in Japan and the U. S of A. The scientists spent sleepless nights looking for ways to curb the impact of seismic activities.
Secondly, there is another technique called base isolation. This uses base isolators to collect the structural elements from the building. The collected elements are later used to decouple other structures of the building when the ground is shaking. Hence, the seismic performance of the elective is enhanced because the integrity of the structure is increased. This technology can thus be applied to other structures to make them withstand earth activities.
Another important technique is called supplementary damping. This is applied by using supplementary dampers to absorb energy or motion during seismic activities. Then the dampers convert the absorbed energy into heat which is damped or released into the other structures of the elective. Thus, the building is not moved by the motion impact. However, the building will eventually become weak due to the damping effect.
Another technique that is employed is called TMD or tuned mass dampers. This method uses movable weights that are on things that look like springs. These are used to reduce wind sway, especially in skyscrapers. The TMDs can thus be used to impart seismic activities in about ten story buildings. The method is active in places that are prone to seismic activities.
The fifth technique is known as slosh tank. Here, a large tank, called a sloshing tank, is filled with a low viscous liquid like water. Then, the tank is taken to a part of the structure that there are lateral motions that are significant, like the roof. It thus counters all the dynamic motions that may take place.
The next technique is known as the active control-system. This method is used in buildings that are extremely tall. Usually, most modern buildings are constructed using materials that are light-weight. Hence, during strong winds and earth movements, the structures may start to sway. This method thus makes the buildings stronger.
These and many other techniques are used today to strengthen buildings. Hence, if you happen to live in areas prone to earth movements, soil failure or strong winds, protect your house. You can use the most appropriate method for your structure. The retrofitting company will advise you on the best.
