Abstract
U ovom završnom radu proveden je proračun statički određene i statički neodređene rešetkaste konstrukcije. U uvodnom dijelu kratko su opisani rešetkasti nosači i način određivanja statičke određenosti. Na jednostavnom primjeru prikazane su metode putem kojih se određuju uzdužne sile u štapovima. Napravljen je proračun uzdužnih sila za zadane rešetkaste nosače. Za statički određen nosač uzdužne sile su određene metodom čvorova, a za statički neodređen nosač korištena je metoda sila. Na osnovu izračunatih vrijednosti uzdužnih sila provedeno je dimenzioniranje poprečnih presjeka štapova s obzirom na uvjet čvrstoće te je za tlačno opterećene štapove dodatno provedena provjera na izvijanje. Nakon toga napravljen je proračun i dimenzioniranje čvornog lima proizvoljno odabranog čvora statički određenog nosača. U posljednjem dijelu rada provedena je numeričke analiza pomoću softvera Ansys APDL čime su provjerena analitički određena rješenja uzdužnih sila u štapovima. Dodatno su određeni i pomaci čvorova statički određene i neodređene rešetke na osnovu kojih je dana usporedba krutosti promatranih rešetki.
Abstract (english)
In this paper, the calculation of a statically determine and statically indeterminate truss girder is performed. The introductory section describes what a truss girder is and the method to establish the static determination. The methods for determining the axial forces in the rods are described on a simple example. The calculation of the axial forces in rod elements was made for a given load. For the statically determinate truss girder the axial forces are obtained throughmethod of joints, while for a statically indeterminate truss girder, method of forces was used. Based on the calculated values of axial forces, the sizing of the cross section of the rods was performed with regard to the strength condition and for the pressure loaded rods, an additional buckling check was performed. After that the calculation and dimensioning of the node sheet of an arbitrarily selected node were performed. In the last part of the paper, numerical analysis was performed using software Ansys APDL by which the analytical determined solutions were checked. Additionally, the displacements of the nodes were determined, and a comparison was given between the stiffness of the truss girders.
