Sažetak
In this paper the procedure for establishing the funicular shape of a polygonal (deck-stiffened, inverted Langer) arch will be discussed. In this type of structure the deck is resisting any tendency to bend or buckle. So the deck is thicker than the arch which carries only pure compression. The funicular shape of an arch coincides with its line of trust which is the set of resultants of the trust and weight each part of an arch imposes on the next lower one. In this way all sections along the axis of the arch are in direct stress and the material required to construct the arch is minimized. For a particular set of loads the arch profile in direct stress is called the funicular arch. The procedure starts with imagining that the loads carried by the arch are applied to a cable. Usually this shape is determined for the dead load. The designer can automatically generate a funicular shape for the loads. If the cable shape is turned upside down, the result is a funicular arch. This type of structure was developed by the Swiss engineer Robert Maillart.
