Earthquake resistant foundation design
Topic outline
-
Overview
Undertaking adequate geotechnical investigations to understand likely ground performance in earthquakes is an essential aspect of good and economic building design.
The Module 4 guideline Earthquake resistant foundation design is part of the series 'Earthquake geotechnical engineering practice guidelines'released by MBIE and NZ Geotechnical Society in 2016.
This course will:
- help you navigate Module 4
- show you where you can find the key information on the topic
- check your knowledge on important aspects of foundation design.

How to complete
New Zealand is a high earthquake hazard region and earthquake considerations are integral to the design of buildings.
Many buildings in the Christchurch CBD were on shallow foundations and some of these were badly affected by liquefaction including excessive settlements and tilting from the Canterbury earthquakes.
Though the level of shaking in the Canterbury earthquakes far exceeded even the ultimate limit state (ULS) design level of shaking, a better understanding of site geotechnical performance during earthquakes is desirable. This should lead to better foundation performance in order to achieve greater resilience and reparability for the building stock.Useful Links
