  2. Base and superstructure - Wikipedia

    en.wikipedia.org/wiki/Base_and_superstructure

    In Marxist theory, societies consist of two parts: the base (or substructure) and superstructure. The base refers to the mode of production which includes the forces and relations of production (e.g. employer–employee work conditions, the technical division of labour , and property relations) into which people enter to produce the necessities ...

  3. Substructure (engineering) - Wikipedia

    en.wikipedia.org/wiki/Substructure_(engineering)

    The substructure of a building transfers the load of the building to the ground and isolates it horizontally from the ground. This includes foundations and basement retaining walls. [1] It is differentiated from the superstructure. It safeguards the building against the forces of wind, uplift, soil pressure etc.

  4. Historical materialism - Wikipedia

    en.wikipedia.org/wiki/Historical_materialism

    G.A. Cohen argues in Karl Marx's Theory of History: A Defence that a society's superstructure stabilizes or entrenches its economic structure, but that the economic base is primary and the superstructure secondary. That said, it is precisely because the superstructure strongly affects the base that the base selects that superstructure.

  5. Superstructure (condensed matter) - Wikipedia

    en.wikipedia.org/wiki/Superstructure_(condensed...

    In solid state physics, a superstructure is some additional structure that is superimposed on a higher symmetry crystalline structure. [1] A typical and important example is ferromagnetic ordering. In a wider sense, the term "superstructure" is applied to polymers and proteins to describe ordering on a length scale larger than that of monomeric ...

    The superstructure of this cargo ship is in the back and includes a lifeboat. The cruiseferry Mega Smeralda. The blue and white part of the ship is the superstructure and the yellow part of the ship is the hull. A superstructure is an upward extension of an existing structure above a

  7. Girder bridge - Wikipedia

    en.wikipedia.org/wiki/Girder_bridge

    The superstructure is everything from the bearing pads, up - it is what supports the loads and is the most visible part of the bridge. The substructure is the foundation which transfers loads from the superstructure to the ground. Both must work together to create a strong, long-lasting bridge. The superstructure consists of several parts:

  8. Dynamic substructuring - Wikipedia

    en.wikipedia.org/wiki/Dynamic_substructuring

    Dynamic Substructuring (DS) is an engineering tool used to model and analyse the dynamics of mechanical systems by means of its components or substructures. Using the dynamic substructuring approach one is able to analyse the dynamic behaviour of substructures separately and to later on calculate the assembled dynamics using coupling procedures.

  9. Substructure (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Substructure_(mathematics)

    A is said to be a substructure of B, or a subalgebra of B, if A is a weak subalgebra of B and, moreover, R A = R B ∩ {\displaystyle \cap } A n for every n -ary relation symbol R in σ. If A is a substructure of B , then B is called a superstructure of A or, especially if A is an induced substructure, an extension of A .
