Abstract

U radu se primjenjuje ideja optimizacije oblika luka i svoda primjenom vlačno-tlačne analogije. Ideja je da se pronađe ravnotežni oblik mreže elemenata u čistom vlaku te se zrcaljenjem oko horizontalne ravnine dobije mreža elemenata u tlaku. Takva mreža može se koristiti za izgradnju lukova i prostornih tlačnih jednoslojnih rešetki. Vlačno-tlačna analogija u radu je obrađena izradom dva fizikalna modela (luk i tlačna prostorna rešetka), te vizualnom usporedbom dobivenih oblika s ravnotežnim oblicima njihovih numeričkih modela. Prilagođenim programskim kodom metode gustoća sila dobiveni su (numerički) ravnotežni položaji luka i tlačne prostorne rešetke.

Abstract (english)

The paper addresses the idea of optimizing the shape of the arch and vault by applying the hanging cloth analogy. The idea is to find an equilibrium shape of a network of elements in a pure tension and by mirroring around a horizontal plane, a network of elements in pressure is obtained. Such a network can be used for the construction of arches and spatial single-layer grid shells. The hanging cloth analogy in this paper is processed by making two physical models (arc and compressive spatial grid shell), and a visual comparison of the obtained shapes with the equilibrium forms of their numerical models. The (numerical) equilibrium shape of the arc and the spatial grid shell are obtained by the adjusted program code of the force density method.
