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.Designing Buildings https://www.designingbuildings.co.uk/wiki/Substructure It is differentiated from the superstructure. It safeguards the building against the forces of wind, uplift, soil pressure etc. It provides a level and firm surface for the construction of superstructure A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstruct .... It also prevents unequal or differential settlement and ensures stability of the building against sliding, overturning, undermine due to floodwater or burrowing animals.

Substructure (mathematics)
In mathematical logic, an (induced) substructure or (induced) subalgebra is a structure whose domain is a subset of that of a bigger structure, and whose functions and relations are restricted to the substructure's domain. Some examples of subalgebras are subgroups, submonoids, subrings, subfields, subalgebras of algebras over a field, or induced subgraphs. Shifting the point of view, the larger structure is called an extension or a superstructure of its substructure. In model theory, the term "submodel" is often used as a synonym for substructure, especially when the context suggests a theory of which both structures are models. In the presence of relations (i.e. for structures such as ordered groups or graphs, whose signature is not functional) it may make sense to relax the conditions on a subalgebra so that the relations on a weak substructure (or weak subalgebra) are ''at most'' those induced from the bigger structure. Subgraphs are an example where the distinction mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
