<h2 class = 'uawtitle'>The Advantage Of Seismic Retrofitting On Buildings</h2><br />
<div style='font-style:italic;' class='uawbyline'>by Peter Fox</div><br /><br />
<div class='uawarticle'>Everywhere there is an old building, its damages are not hidden. The crevices and its cracks on its surfaces that makes it look weak and dangerous. One reason why damages on building are often seen is seismic activities. This is the movements below the ground or so called earthquake. The shaking caused by this natural disaster affects the structure of a building and sometimes even destroying it. In addition, the ground or soil where a structure is built can also be deformed making it not a great base for skyscrapers anymore.<br />
<br />
<a href="https://www.feiassociates.com/soft-story-apartments/">Apartment buildings seismic retrofit</a> where the current structures of apartments are improved to allow it to stand against natural disturbances. Good thing, there has been this method that was used when developing the structure of a building to make it resistant to natural hazards like cyclones, tornadoes and including earthquake. This reduces the damages during calamities.<br />
<br />
There are several countries that are surrounded with tectonic plates, an example would be Japan. Usually homes and apartments that is built around there are prone to damages when the constant shaking occurs. Annually, the numbers of homes that are destroyed due to seismic activities are growing rapid.<br />
<br />
This retrofitting method actually started during the late nineties in few countries like USA and Japan. But, during that period it was not yet well developed and modified. The details were just so basic and often does not promote over all protection. But lot of architects and engineers thought of how improving such method in the longer run.<br />
<br />
Techniques overtime did not became stagnant on just one method alone, there has been a lot of experiments to make sure what is best amongst the rest. Like example, strengthening. This method is done by putting cross braces on walls as well as structural walls to improve its capacity to stand against disasters.<br />
<br />
These braces hold tight grips of some parts that is considered to be the weakest. In Japan, buildings are often with steel tendons, these are high strength and is has moment resisting capacity. This method is one of the few techniques that was used when the idea of retrofitting started to get acknowledged by different countries. In California, there was actually a bridge that used the same system.<br />
<br />
Next technique is known, supplementary damping. This uses a base isolation system which means it is the soil that serves as base that is made capable of supporting the entire infrastructure. The protection is down below and not on the actual apartment. The vibration is absorbed by the ground so that the shaking on the higher parts is reduced.<br />
<br />
The supplementary dampers are used to absorb energy caused by the swaying and turn it into heat. This method also lessens displacement and acceleration of the building, as a result the threat of damage is not that huge. In simpler words, dampers serves as shock absorbers down below.<br />
<br />
Few method would depend on the individual material used. If high capacity components are present then the stiffness of which would probably help in protecting the building as a whole. Old apartments that are improved through retrofitting does not have to be fully renovated though, some parts are just strengthen.<br />
