Abstract
The importance of ensuring that dam
structures can withstand earthquakes has been recognized and
practiced for many years. The technical capability of the
dam engineering industry in the seismic design of dam
structures has increased considerably since the 1980-1990s.
Dams designed using modern seismic engineering principles
that are well constructed have performed well during
earthquakes, with only modest damage. Older dams that have
suffered damage from earthquakes are likely to have been
subjected to poor construction or maintenance, or they lack
modern defensive design measures to prevent failure. Seismic
hazard varies around the world. Some countries experience
major earthquakes frequently, whereas other countries have
hardly ever experienced one. This technical note contains
the minimum level of technical detail for seismic design of
new structures and seismic assessment of existing
structures, so that non-specialists can use it. The key
objective is to provide guidance for addressing seismic
aspects of dam projects early on in project preparation. The
note is intended to raise awareness and inform specific
studies and investigations, as appropriate, during project
preparation. The material presented should be used to assess
the required level of seismic hazard assessment, review the
adequacy of the dam’s seismic design and resilience
measures, and recommend required expertise for quality
assurance of projects involving dams in seismic areas.
