Abstract

U ovom radu je uspoređeno i analizirano više idejnih rješenja krovišta stadiona upotrebom mreže prednapetih kabela. Izvršeno je traženje ravnotežnog oblika pomoću metode gustoće sila te je opisana problematika procesa nalaženja oblika. Prilikom oblikovanja krovišta pažnja je bila posvećena mnogim prostorno – funkcionalnim ograničenjima realne konstrukcije stadiona i njene okoline. Osim toga, izvršen je nelinearni statički proračun dvije različite mreže kabela pod djelovanjem prednaponskih sila , vlastite težine te aproksimativnog opterećenja vjetrom i snijegom. Opisana je korekcija prednaponskih sila ukoliko dođe do njihova gubitka, a na kraju su interpretirani rezultati progiba i uzdužnih sila.

Abstract (english)

In this thesis it have been compared and analyized few conceptual solutions of a stadium roof using pretensioned cable net. Form finding was conducted using force density method and problems during that process have been described. During modeling process of the roof, it has been paid attention to many spatial – functional limitations of a real stadium structure and its environment. Furthermore, it has been conducted nonlinear analysis for two different cable nets subjected to pretension forces, self weight and approximately determined wind and snow load. It has been described correction of the pretension forces if their loss ever occur and in the end, results of a sag and axial forces have been interpreted.
