ABSTRACT

Any non-funicular structure can be converted into an axial-only geometry with the introduction of additional loads through an external post-tensioning system. This design approach would provide architectural versatility without giving up on structural efficiency. This paper presents a physical validation of this methodology through reduced-scale models. After a brief overview and characterization of physical models, this paper illustrates physical modeling, testing, and validation of reduced-scale structures where additional loads are applied to convert them into funicular shapes. The structures are modelled through a combination of compressive geometries fabricated through additive manufacturing (3D printing) and post-tensioning systems constructed with thin wire and precise laser-cut connecting elements. Experimental testing provides a first physical validation of the method and insights about the structural behaviour of these structures.
