OPTIMIZATION OF A STEEL TRUSSES

Kako i sam naslov navodi, u ovom završnom radu optimizirana je rešetkasta čelična konstrukcija, odnosno nadstrešnice. Tehnološki dio ovisi o ograničenjima spajanja dijelova (profila, tj. cijevi), spajanja konstrukcije s okolinom te utjecaj okoline na samu konstrukcije. Numerički dio okvirne konstrukcije kao nosivog dijela krova proveden je kroz algoritam u programu Excel koji se slaže po EUROCODE EN 1993-1-8:2005 normi. Proračunati su zavareni i vijčani spojevi, odnosno pronađena je optimalna konstrukcija koja zadovoljava kriterij opterećenja (mase) i cijene obrade dijelova i spajanja istih. Na kraju je prikaz same konstrukcije u sastavnom crtežu i 3D modelu.As the title itself states, in this final paper, steel truss, ie the carport has ben optimized. The technological part depends on the limitations of connecting parts (profiles, ie pipes), connecting the structure with the environment and the impact of the environment on the structure itself. The numerical part of the frame structure as a load-bearing part of the roof is carried out through an algorithm in Excel that complies with the Eurocode EN 1993-1-8: 2005 standard. Welded and bolted joints were calculated and the optimal construction was found that satisfies the criterion of load (mass) and the price of processing parts and joining them. Finally, there is a presentation of the structure itself in a composite drawing and a 3D model
