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.

Municipal Services Building in Glendale, California retrofitted with base isolation.

Seismic retrofit performance objectives

[change | change source]

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.
