Abstract

Cilj ovog završnog rada je strukturna analiza plovnog pristana za unutarnje vode.
Prva faza se sastoji od upoznavanja s relevantnim pravilima Hrvatskog registra brodova (HRB) za
dimenzioniranje elemenata brodskog trupa i za proračun dinamičkih komponenti opterećenja za
područje plovidbe IWW = 0.6.
Druga faza projektiranja se sastoji od izrade cijelog modela pristana metodom konačnih elemenata
(MKE) na temelju postojećeg CAD modela pristana i preliminarnih dimenzija konstrukcijskih
elemenata glavnog rebra.
U trećoj fazi MKE model je opterećen globalnim opterećenjem prema pravilima HRB, u slučaju
maksimalnog pregiba i maksimalnog progiba, te se provela statička linearna analiza strukturnog
odziva korištenjem metode konačnih elemenata.
Posljednja faza sastoji se od analize distribucije primarnih naprezanja po visini broda i ocjene
podobnosti originalnog prijedloga rješenja konstrukcije na razini dopuštenih naprezanja i kriterija
izvijanja. U slučaju nezadovoljenja kriterija čvrstoće provedeno je redimenzioniranje
konstrukcijskih elemenata te je dan prijedlog zadovoljavajućeg rješenja.

Abstract (english)

The subject of this project is conducting a structural analysis of a river floating dock.
The first phase involves familiarizing themselves with the relevant rules of the Croatian Register
of Ships (CRS) for dimensioning the elements of the ship's hull and calculating the dynamic
components of the load for the navigation area IWW = 0.6.
The second phase of the design consists of creating the entire dock model using the finite element
method based on the existing CAD model of the dock and the preliminary structural dimensions
of the midship section.
In the third phase, it is necessary to load the model with global loads according to the CRS rules,
considering the case of maximum bending and maximum deflection, and to perform a static linear
analysis using the finite element method.
The final phase involves analysing the distribution of primary stresses along the height of the ship
and evaluating the suitability of the original proposed structural solution in terms of allowable
stresses and buckling criteria. If the yield or buckling criteria are not met, the structural elements
must be redesigned, and a satisfactory solution has been proposed.
