Abstract

Prednapete mreže kabela su gipke vlačne konstrukcije. Uže kao konstruktivni element
opterećenja prenosi isključivo pojavom uravnotežujućih vlačnih sila. Užad se prednapinje i
slaže u mreže kako bi se osigurala geometrijska krutost i pojava isključivo vlačnih sila pri bilo
kojoj kombinaciji opterećenja. Nalaženje oblika prednapetih mreža kabela je primarni
zadatak projektanta, a najpovoljniji način za to je primjena metode gustoća sila. Metoda
gustoća sila linearizirala je do tad nelinearan proračun i značajno olakšala projektiranje. U
primjerima je prikazano nalaženje oblika mreža kabela uporabom metode gustoća sila kroz
iteracije pomoću programskog paketa FALCON.

Abstract (english)

Cable nets are flexible tensile structures. Cable, as a structural element, transfers the load
exclusively through the development of balancing tensile forces. The ropes are pretensioned
and arranged into nets to ensure geometric stiffness and the occurrence of
purely tensile forces under any load combination. Form-finding of the pre-tensioned cable
nets is the primary task of the engineer, and the most favorable way to achieve this is by
applying the force density method. The force density method linearized the previously
nonlinear calculations and significantly simplified the design process. Examples are shown
for determining the shape of cable nets using the force density method through iterations
with the FALCON software package.
