Webb1 feb. 2024 · The section above has discussed the method of obtaining a bridge's frequencies and mode shapes by the virtual contact-point response. However, the … WebbIn a “classical” vertical planar arch bridge subjected only to in-plane loads, its funicular geometry (which is the geometry that results in an equilibrium state free from bending stresses, i.e., simply under axial forces) is contained within a vertical plane. In the so-called “spatial arch bridges,” their structural behavior extends from the essentially vertical in …
