Abstract

U završnom radu obrađena je tema Aksijalno udarno opterećenje štapova, sveobuhvatnom analizom njegovih teorijskih osnova, metodom proračuna i praktičnim situacijama. Teorijski dio rada opisuje problematiku aksijalnih djelovanja na različite vrste štapova i štapnih sustava. Promatraju se slučajevi u kojima se određuju statička i dinamička produljenja i naprezanja ovisno o promjeni različitih parametara štapa. Svaki slučaj potkrijepljen je matematičkim izrazima i ilustracijama. Metode proračuna dane u teorijskom dijelu primjenjujemo u praktičnom zadatku. Riješeni zadatak prikazuje i jedan realan problem iz prakse. Promatramo krovnu konstrukciju u gorskom dijelu Republike Hrvatske s koje se urušava snijeg na rešetkastu krovnu konstrukciju koja je na visini nižoj za 2 metra. Matematički izračuni, popraćeni grafičkim prikazima pokazuju nam ovisnost statičkih i dinamičkih naprezanja o promjeni površine poprečnog presjeka štapova u rešetci. Ovo istraživanje nam pobliže dočarava objašnjava aksijalna naprezanja i produljenja štapova, nudeći inženjerima i istraživačima teorijskom i praktično znanje u daljnjim analizama.

Abstract (english)

In this final paper, the topic of axial impact loading of bars has been studied with comprehensive analysis of its theoretical foundations, calculation method and practical situations. Theoretical part of the paper describes the problem of axial actions on different types of bars and bar systems. Cases in which static and dynamic elongations and stresses are determined depending on the change of various parameters of the bars have been observed in this paper. Each case is presented with mathematical expressions and illustrations. The calculation methods mentioned in the theoretical part has been applied in the practical task. The solved task also shows a realistic problem from practice. We are observing the roof structure in the mountainous part of the Republic of Croatia, from which the snow is falling onto the lattice roof construction located 2 meters below the roof structure. Mathematical calculations, accompanied by graphical representations, show us the dependence of static and dynamic stresses on the change in the cross-sectional area of the bars in the lattice. This research more closely evokes and explains the axial stresses and elongations of the bars, offering engineers and researchers theoretical and practical knowledge in further analyses.
