Promene na konstrukcijama mogu izazvati promene u strukturnim matricama nekih elemenata. U zavisnosti od vrste konstrukcije, kao i od željenih promena u njoj, moguće je menjati veću ili manju grupu elemenata. U ovom radu se analiziraju efekti malih i velikih modifikacija grupa elemenata na sopstvene vrednosti i frekvencije. Analiza se vrši korišćenjem kompjuterskih programa zasnovanim na metodi konačnih elemenata i implementaciji distribucije potencijalne i kinetičke energije na glavnim oblicima oscilovanja u posmatranim elementima konstrukcije.Structural modifications can cause changes in the matrices of some elements. Depending on the type of structure, or a desired change, a group of elements can be modified. This paper analyzes the effe...
