Seismic retrofitting is the process that is used to modify existing buildings to be more resistant to seismic activities. Also, this technique makes the building more resistant to soil failure and ground motion. Therefore, the structures will not be affected in case of any seismic activities. Most people are now demanding for this technique, especially in urban settings. This has led to the establishment of so many earthquake retrofit companies. This is because of the high demand. There are several techniques used for the retrofitting. Some of the most common ones are listed below.
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.
The third method is by the use of supplementary dampers. These dampers absorb the energy and motion during seismic activities. The absorbed energy is converted to heat. Therefore, the effects are damped into the structures that are attached to the ground rigidly. Nevertheless, when the damping process continues for several years, the building can become weak. All in all, this is also a very effective technique.
Another critical technique used is called TMD. This is a technique that employs tuned mass-dampers. Here, movable weights attached to spring-like things are used. These mass dampers are normally used in very tall buildings to reduce the wind sway. Therefore, this technique can also be used in seven to ten several buildings. They thus impart seismic activities in tall buildings located in areas that highly prone to earth movements.
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.
