1Seismic 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… …
2Seismic 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,… …

4Teller-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… …
5Teller–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… …
6Earthquake engineering — is the study of the behavior of buildings and structures subject to seismic loading. It is a subset of both structural and civil engineering.The main objectives of earthquake engineering are: * Understand the interaction between buildings or… …
7Soil structure interaction — Most of the civil engineering structures involve some type of structural element with direct contact with ground. When the external forces, such as earthquakes, act on these systems, neither the structural displacements nor the ground… …

9Peak ground acceleration — (PGA) is a measure of earthquake acceleration on the ground and an important input parameter for earthquake engineering, also known as the design basis earthquake ground motion (DBEGM)[1] Unlike the Richter and moment magnitude scales, it is not… …
10High performance fiber reinforced cementitious composites — (HPFRCCs) are a group of fiber reinforced cement based composites which possess the unique ability to flex and self strengthen before fracturing. This particular class of concrete was developed with the goal of solving the structural problems… …
