Abstract

Utjecajna linija grafički je prikaz utjecajne funkcije koja opisuje promjenu učinka djelovanja na nosaču ovisno o položaju opterećenja. Utjecajnu liniju određujemo statičkim postupkom, postavljanjem jednadžbi ravnoteže čime ju prikazujemo kao funkciju položaja jedinične sile na nosaču ili kinematičkim postupkom u kojem je one definirana planom pomaka mehanizma s jednim stupnjem slobode nastalog oslobađanjem tražene sile zbog odgovarajućeg jediničnog pomaka. U radu su pobliže objašnjeni i prikazani načini određivanja utjecajnih linija za trozglobne sisteme, sisteme sa zategama, ojačane grede te poduprte i ovješene sisteme statičkim i kinematičkim postupkom.

Abstract (english)

The influence line is a graphic representation of the influence function, which describes the change in effect of action on a truss depending on the position of the load. Influence lines can be determined by a static method, by setting the equilibrium equations, which show them as a function of the position of the unit force on the girder, or by a kinematic method, where they are defined by the displacement plan of the mechanism with one degree of freedom created by the release of the required force due to an appropriate unit displacement. In this paper, the ways of determining influence lines for three-hinged systems, tied systems, Langer beams, and proped up and suspended systems by static and kinematic procedures are explained and presented in more detail.
