The methods used to seismically retrofit a building are: beam addition method, seismic wall addition method, support point adding method, and
seismic isolation method.
In construction of a building, seismically retrofitting or earthquake retrofitting is commonly done. The major reason to why it is done is to prevent displacement from the structure's foundation.
When seismically retrofitting is done, a building is considered safer and less likely to suffer damage when earthquake or any seismic forces strike.
So a retrofit is worth it as it will strengthen a building or an house against shake damage to help people living in it to remain safe and less worried. The following methods can therefore be used to provide a retrofit or to seismically retrofit a building:
Beam addition method
This is done by adding beams between the main girders of the existing reinforced concrete to improve the load carrying capacity of the reinforced concrete.
Seismic wall addition method
This is done by placing new reinforced concrete walls between existing ones and bonding them to improve load carrying capacity as a structural body
Support point adding method
This is done by supporting sections of beams and other existing concrete members with new members to reduce the span of members
Seismic isolation method
This is done by using seismic isolation bearings to reduce the seismic energy applied to the structure. This will improve the building's performance values during an earthquake.
