Final answer:
Seismic retrofitting is the process of strengthening existing buildings and structures to make them more resistant to earthquakes. It helps reduce the risk of building collapse and damage during seismic events.
Step-by-step explanation:
Seismic retrofitting is the process of strengthening existing buildings and structures. It involves making modifications to buildings to make them more resistant to earthquake-induced vibrations and forces. These modifications can include adding additional support elements, such as braces and shear walls, to increase the structural integrity of the building.
Seismic retrofitting is an important practice in areas prone to earthquakes, as it helps to reduce the risk of building collapse and damage during seismic events. By strengthening the buildings, the potential for injuries and loss of life can be significantly decreased.
