construction element in the form of a beam whose height constitutes a considerable part of the span that it covers. Webs, usually having a right-angled cross section, are used in reinforced concrete components of industrial buildings, elevators, and the like. The distribution of stresses in webs differs from the distribution of stresses in ordinary beams; the normal stresses in the cross sections of webs are distributed according to a curvilinear law, with the neutral axis (during application of a vertical load) located closer to the tensed edge of the cross section. Webs are calculated by the methods of the theory of elasticity.
What does it mean when you dream about a web?
Dreaming about being caught in a web is likely a straightforward representation of some sticky situation we feel caught in, or that we might get caught in. We also talk about a “web of lies” or “a tangled web.” In the contemporary world, dreaming about a spider web might be a symbolic way of referring to the Internet—the “worldwide web.”
