Abstract

U uvodu je objašnjena zamisao metode pomaka. Zatim su detaljno opisane obje metode, metoda pomaka i inženjerska metoda pomaka te su definirani svi pojmovi korišteni u zadatku. Opise prate objašnjenja, skice i postupak rješavanja pojedine metode s izvodima i formulama. Prethodno napisano potkrijepljeno je primjenom metode na jednostavnim ravninskim okvirnim sustavima. Rad sadrži dva primjera riješena točnom metodom pomaka (u drugom primjeru je aksijalna krutost elemenata trideset puta veća u odnosu na prvi) i jedan primjer riješen inženjerskom metodom pomaka. Dobivenim rezultatima (poopćeni pomaci i unutarnje sile) predočavamo koliko inženjerska metoda pomaka (malo) odstupa u odnosu na točnu metodu pomaka, odnosno kolika će biti razlika u rezultatima ako se zanemari utjecaj promjene duljine štapova uslijed uzdužne sile, što odgovara znatnom povećanju aksijalne krutosti štapa.

Abstract (english)

Introduction contains general idea of displacement method. Furthermore, detailed descriptions of displacement method and engineering displacement method are given and all terms in examples are defined. The descriptions are followed by explanations, sketches and procedure of each method with statements and formulas. The foregoing is substantiated by the application of the methods on simple frame systems in plane. The paper contains two examples solved using displacement method (in the second example the axial stiffness of elements is thirty times higher than in the first one) and one example solved using engineering displacement method. The results obtained (generalized displacements and internal forces) indicate how much (or little) the engineering displacement method deviates from the exact displacement method, or how much results are differenced if the change of beams length due to longitudinal force is neglected, which corresponds to a significant increase of beams axial stiffness.
