Abstract
U završnom radu prikazane su metode proračuna pomaka na statički neodređenim nosačima. Da bi izračunali pomake i sile na statički neodređenom sustavu bitna je veza između unutarnjih sila i pomaka, odnosno deformacije nosača. U radu su prikazani računski primjeri određivanja pomaka na statički neodređenim sustavima metodom pomaka i metodom sila sa i bez upotrebe redukcijskoga stavka, te grafoanalitička metoda. Analitički proračunati pomaci navedenim metodama su uspoređeni sa numerički izračunatim pomacima pomoću Autodesk Robot Structural Analysis.In the final paper, the methods of displacement calculation on statically indeterminate girders are presented. In order to calculate the displacements and forces on a statically indeterminate system, the connection between the internal forces and the displacements, ie the deformation of the girder, is important. The paper presents computational examples of determining the displacement on statically indeterminate systems by the displacement method and the force method with and without the use of a reduction item, and the graphoanalytical method. Analytically calculated offsets by these methods were compared with numerically calculated offsets using Autodesk Robot Structural Analysis
