List of international earthquake acceleration coefficients

Main article: Earthquake engineering

List of international earthquake acceleration coefficients. A list of earthquake coefficients used in structural design for earthquake engineering[1] around the world. For example, a coefficient of 0.09 indicates that a building is designed that 0.09457 of its weight can be applied horizontally during an earthquake.

Australia

From Australian Standard 1170.4. Coefficients are based on 10% chance exceedence in 50 years.

Note: Meckering, Western Australia, has the largest coefficient in Australia of 0.22.

Greece

From ΕAΚ 2003 building code

  • Zone 1 = 0.16g (Thrace and most of Northern Greece, Parts of Athens and Parts of Thessaloniki)
  • Zone 2 = 0.24g (Parts of Athens and Parts of Thessaloniki)
  • Zone 3 = 0.36g (Zakynthos Island, Cephalonia Island)

United States

Earthquake acceleration coefficients are calculated from the Seismic Ground Motion maps in Chapter 22 of ASCE 7,[2] which are generally adopted in states and municipalities through the International Building Code. Coefficients can be found in the ASCE Hazard Tool online.[3]
