![]() In contrast to a funicular shape, forces may not be able to act in pure tension or compression under self-weight, and bending moments inevitably arise, increasing the structural material required. However, non-structural conditions, such as esthetics, functionality, and geotechnical issues, often prohibit selection of a structurally ideal funicular shape in which only axial forces are activated (the word funicular is independently used for only compression or tension curves). In the design of curved structures, the overall shape, usually decided in conceptual design, is a key contributor to the overall cost and structural efficiency. ![]()
