The IEEE 693: Recommended Practice for Seismic Design of Substations. [ 1 ] is a Institute of Electrical and Electronics Engineers standard. This standard is recognized also by American National Standards Institute , and is used mainly in the American Continent.
Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design, earthquake engineering or structural assessment and retrofit (see structural engineering) in regions where earthquakes are prevalent.
Seismic design requirements depend on the type of the structure, locality of the project and its authorities which stipulate applicable seismic design codes and criteria. [7] For instance, California Department of Transportation 's requirements called The Seismic Design Criteria (SDC) and aimed at the design of new bridges in California [ 37 ...

The 1940 seismic code was developed in response to the 1939 Erzincan earthquake which killed 32,000 people. It drew parallels with Italy's seismic codes at the time. A seismic zonation map was also developed in 1942 which assessed the seismic hazard of all Turkish provinces on three levels; "hazardous", "less hazardous" and "no hazard".
Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales , which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking.
PGA is an important parameter (also known as an intensity measure) for earthquake engineering, The design basis earthquake ground motion (DBEGM) [2] is often defined in terms of PGA. Unlike the Richter and moment magnitude scales, it is not a measure of the total energy (magnitude, or size) of an earthquake, but rather of how much the earth ...
