Abstract

Ovaj rad bavi se analizom proračuna i dimenzioniranja armiranobetonskog telekomunikacijskog tornja pod djelovanjem vjetrovnog i drugih opterećenja, s naglaskom na usporedbu njemačkih normi DIN i europskih normi EN 1991-1-4. Kroz konkretan primjer tornja na Sljemenu, prikazani su postupci proračuna vjetra, statičkih i dinamičkih sila te seizmičkih opterećenja. Rezultati su analizirani usporedbom tradicionalnog pristupa prema DIN-u i suvremenog nelinearnog proračuna prema EN-u. Kroz nelinearnu analizu dobivene su preciznije vrijednosti deformacija i naprezanja, osobito na višim dijelovima tornja, što je rezultiralo boljim uvidom u stvarno ponašanje konstrukcije. Na temelju rezultata, preporučen je europski pristup zbog veće preciznosti u proračunu visokih konstrukcija izloženih promjenjivim uvjetima. Rad naglašava važnost pravilnog dimenzioniranja i proračuna za stabilnost i sigurnost konstrukcija u telekomunikacijskom sektoru.

Abstract (english)

This paper deals with the analysis of calculation and dimensioning of a reinforced concrete telecommunications tower under the action of wind and other loads, with an emphasis on the comparison of the German standards DIN and the European standards EN 1991-1-4. Through the concrete example of the tower on Sljemen, the calculation procedures of wind, static and dynamic forces and seismic loads are presented. The results were analyzed by comparing the traditional approach according to DIN and the modern nonlinear calculation according to EN. Through non-linear analysis, more precise values of deformations and stresses were obtained, especially on the higher parts of the tower, which resulted in a better insight into the actual behavior of the structure. Based on the results, the European approach was recommended due to greater precision in the calculation of tall structures exposed to changing conditions. The paper emphasizes the importance of proper dimensioning and budgeting for the stability and safety of structures in the telecommunications sector.
