Bois d'œuvre

thumb|upright=1.5|Structure construite en bois. Le bois est un matériau de construction employé dans la construction des bâtiments. thumb|upright=1.5|Parties du bois d'œuvre. La construction fait appel au duramen, appelé aussi « bois parfait » ou « bois de cœur », qui constitue la partie centrale de l’arbre. Le duramen est biologiquement quasi-inerte et plus durable que l’aubier — celui-ci, souvent plus clair et léger, étant constitué de cellules vivantes. L'aubier est plus facilement et rapidement attaqué par les insectes, bactéries et champignons.

Seismic analysis

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. As seen in the figure, a building has the potential to 'wave' back and forth during an earthquake (or even a severe wind storm). This is called the 'fundamental mode', and is the lowest frequency of building response.

Finite element method in structural mechanics

The finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by a set of appropriate finite elements interconnected at discrete points called nodes. Elements may have physical properties such as thickness, coefficient of thermal expansion, density, Young's modulus, shear modulus and Poisson's ratio.

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. With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries (US, Japan etc.) and late 1970s for many other parts of the world (Turkey, China etc.
