NUMERICAL ANALYSIS AND OPTIMIZATION OF RAILWAY BRIDGE

U radu je analizirana konstrukcija čeličnog željezničkog mosta. Konstrukcija se sastoji od grede i luka, a oni su povezani profilima te skupa čine rešetkasti sklop. Zadatak ovog diplomskog rada podijeljen je u dva dijela. Zadatkom prvog dijela je trebalo odrediti unutrašnje sile u pojedinim elementima konstrukcije mosta, izvršiti odabir profila i proračun oblika luka. Budući da je moguće ponekad ostvariti stanovite uštede, u drugom se dijelu uz pomoć programskog paketa ANSYS izvršilo optimiranje konstrukcije mosta.The paper analyzes the construction of a steel railway bridge. The bridge is conceived as such with a beam and an arch connected by a lattice as the basic bearing elements and profiles which together form a lattice assembly. The task of this thesis is divided into two parts. The task of the first part was to determine the internal forces, select the profile and calculate the shape of the arc. Since certain savings can sometimes be made possible, in the second part, with the help of the ANSYS software package, optimization of the bridge construction was performed
