Girder

A girder /ˈɡɜːrdər/ is a support beam used in construction.[1] It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web, but may also have a box shape, Z shape, or other forms. A girder is commonly used to build bridges.

For the DC Comics character with this name, see Girder (comics).
Ceiling of Hinkle Fieldhouse in Indianapolis, Indiana, is constructed of large trusses built of riveted girders

A girt is a vertically aligned girder placed to resist sheer loads.

Small steel girders are rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders, welded or bolted together from separate pieces of steel plate.[2]

The Warren type girder replaces the solid web with an open latticework truss between the flanges. This arrangement combines strength with economy of materials, minimizing weight and thereby reducing loads and expense. Patented in 1848 by its designers James Warren and Willoughby Theobald Monzani, its structure consists of longitudinal members joined only by angled cross-members, forming alternately inverted equilateral triangle-shaped spaces along its length, ensuring that no individual strut, beam, or tie is subject to bending or torsional straining forces, but only to tension or compression. It is an improvement over the Neville truss, which uses a spacing configuration of isosceles triangles.

gollark: Basically, your simple English description of what you want implicitly assumes a bunch of human knowledge - *specialized expert* human knowledge, even - which would require vast amounts of difficult development to get in an AI.
gollark: Oh, and if it's a paper it might not even come with code or it might be really awful code, yes.
gollark: The code/paper you find isn't going to be conveniently usable by just downloading it and copypasting it into your AI's code or something. You'll probably have to actually understand how it works, yet another unfathomable general intelligence task, figure out how it interfaces with the rest of the code or if it can even be used together at all, and possibly rewrite it entirely to fit with what you need.
gollark: "Pluck it out" is also easy to say, but it's actually even harder.
gollark: "Find useful stuff" also sounds pleasantly easy, but it's *not*. Even a human reading a repository or paper may struggle to find "useful" bits; reasoning about the relevance of a new set of information or methods for a project is a difficult general intelligence task.
