Seismic retrofit

From Simple English Wikipedia, the free encyclopedia

Seismic retrofitting is the modification of buildings that already exist to make them resistant to earthquakes.[1] Seismic retrofitting techniques can be applied to other kinds of natural disasters such as tornadoes and strong winds from thunderstorms.

Seismic retrofit performance objectives[change]

Main levels of retrofitted building structure performance [2] objectives may vary, namely:

  • To protect human lives.
  • To protect a structure from total failure.
  • To preserve a structure's functionality after a strong earthquake.
  • To make a structure, practically, unaffected by any earthquake.
