Abstract

Završni rad prikazuje primjenu metode specifične za traženje ravnotežnog oblika prednapetih mreža kabela. Naziv metode je metode gustoća sila. Rad opisuje metodu gustoća sila kroz definiranje ležajnih uvjeta, gustoća sila i povezanosti čvorova. Osnovna formulacija metode nije iteracijska, ali se može iteracijski primijeniti. Tako se kroz više koraka određuje, uvođenjem kinematičkih ograničenja (u obliku željenih konačnih vrijednosti sila u elementima ili konačnih duljina elemenata) povoljniji (s obzirom na različite kriterije) ravnotežni oblik mreže prednapetih kabela. U radu se navedena iteracijska primjena metode gustoća sila opisuje kroz dva primjera.

Abstract (english)

The paper presents the application of a method specific for finding the equilibrium shape of prestressed cable nets. The name of the method is the force density method. The paper describes the method through the definition of support points, elements force density and node connectivity. The basic formulation of the method is not iterative, but it can be applied iteratively. In this way, a more favorable (considering different criteria) equilibrium shape of the prestressed cable nets is determined through several steps, by introducing kinematic constraints (in the form of desired final values of forces in elements or final lengths of elements). The mentioned iterative application of the force density method is described through two examples.
