Why move towards Performance Based Earthquake Engineering?
Ř Improved provisions in the Building Codes have reduced “lives
lost” in last two major Earthquakes in
California (1989, 1994) but,
Ř Magnitude of economic losses keeps increasing in each
major earthquake ($7b –Loma Prieta, $15b – Northridge)
Ř Need to focus on functionality, business interruptions, and
losses to non-structural components ~ Limit
losses
