List of international earthquake acceleration coefficients

Last updated

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.[ clarification needed ]

Contents

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

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]
