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.
The first technique is called external post-tensioning. This method has been there for decades. Therefore, it is not new. This method has been approved by the PRESS, which is Precast Seismic Structural Systems in full. This is a large joint research program that is found in the United States and Japan. The eternal post-tensioning is thus one of the methods used to make buildings stronger to resist earthquakes.
Base isolation is the second method. It is applied by using base isolators. These isolators collect any structural elements of an elective and use them in decoupling the building. This means that the others building structures become intact even when there are ground movements. Therefore, this method enhances the integrity as well as seismic performance of the electives. Hence, if you live in with frequent earthquakes, this technique will protect your building.
The third technique is applied using supplementary dampers. During motions in the ground, these supplementary dampers absorb the energy. The energy that is absorbed is then converted to heat. The effects are then damped into the building structures. The building thus remains intact. Nonetheless, continued damping of the heat to the building structures will make it weak overtime.
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.
Another technique called slosh tank is used. A large slosh tank is used here. Then, water or another low viscous liquid is used to fill the tank. Then, this tank is taken to the rooftop and placed there. This is because the roof is prone to lateral motions. This tank thus counters the lateral motions that might 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.
More techniques can be used to inhibit seismic activities in buildings. For the people who are living in areas that are prone to ground disturbances and strong winds, it is essential to protect their structures in advance. This is because these seismic activities can create huge losses that people may never be able to recover from.
