Seismic retrofit — Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. Other retrofit techniques are applicable to areas subject to tropical cyclones,… … Wikipedia
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… … Wikipedia
Seismic hazard — refers to the study of expected earthquake ground motions at the earth s surface, and its likely effects on existing natural conditions and man made structures for public safety considerations; the results of such studies are published as seismic … Wikipedia
Seismic risk — uses the results of a seismic hazard analysis, and includes both consequence and probability. A building located in a region of high seismic hazard is at lower risk if it is built to sound seismic engineering principles. On the other hand, a… … Wikipedia
Seismic performance — Earthquake or seismic performance is an execution of a building s or structure s ability to sustain their due functions, such as its safety and serviceability, at and after a particular earthquake exposure. A structure is, normally, considered… … Wikipedia
Design basis accident — A design basis accident (DBA) or maximum credible accident (MCA)[1] is a postulated accident that a nuclear facility must be designed and built to withstand without loss to the systems, structures, and components necessary to assure public health … Wikipedia
China Seismic Intensity Scale — The China Seismic Intensity Scale (CSIS) is a national standard in the People s Republic of China[1] used to measure seismic intensity. Similar to EMS 92 on which CSIS drew reference, seismic impacts are classified into 12 degrees of intensity,… … Wikipedia
China Seismic Intensity Scale — Die Chinesische seismische Intensitätsskala oder China Seismic Intensity Scale, kurz CSIS oder nicht ganz präzise Liedu Skala,[1] ist ein nationaler Standard für die Bemessung der seismischen Intensität von Erdbeben in der Volksrepublik China.… … Deutsch Wikipedia
Teller-Ulam design — The Teller–Ulam design is a nuclear weapon design which is used in megaton range thermonuclear weapons, and is more colloquially referred to as the secret of the hydrogen bomb . It is named after two of its chief contributors, Hungarian born… … Wikipedia
Mitigation of seismic motion — Main article: Earthquake engineering Mitigation of seismic motion is an important factor in earthquake engineering and construction in earthquake prone areas. The destabilizing action of an earthquake on constructions may be direct (seismic… … Wikipedia
Teller–Ulam design — The basics of the Teller–Ulam design. Radiation from a primary fission bomb compresses a secondary section containing both fission and fusion fuel. The compressed secondary is heated from within by a second fission explosion. The Teller–Ulam… … Wikipedia
