Learn about the different methods of seismic analysis, such as equivalent static, response spectrum, linear dynamic, nonlinear static and time history analysis. Find out how seismic analysis is used in structural design, earthquake engineering and assessment of buildings and nonbuilding structures.
Seismic hazard is the probability of earthquakes and ground motion in a given area and time. Learn how seismic hazard is estimated, measured and mapped, and how it differs from seismic risk and MCEs.
An earthquake is the shaking of the Earth's surface caused by a sudden release of energy in the lithosphere. Learn about the different types of faults, the causes of earthquakes, the effects of earthquakes on the environment and society, and some of the most devastating earthquakes in history.
Learn about the exchange of mutual stress between soil and structure, and how it affects the seismic response of buildings. Find out the types of foundations, the design codes, and the examples of SSI effects in recent earthquakes.
Learn about the interdisciplinary branch of engineering that designs and analyzes structures to withstand earthquakes. Find out the basic concepts, methods, and applications of earthquake engineering, as well as its history and research.
Earthquake prediction is a branch of seismology that aims to specify the time, location, and magnitude of future earthquakes. However, it is a controversial and difficult field, as there have been no successful predictions of large earthquakes and many false alarms or legal consequences.
Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics , stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other ...
Seismic retrofit is the modification of existing structures to make them more resistant to earthquakes. The web page explains various strategies, techniques and performance objectives of seismic retrofit, but does not mention cripple wall, a type of wall used in wood-frame construction.
