Dynamic stiffness method in the vibration analysis of circular cylindrical shell / Metoda dinamičke krutosti u analizi vibracija kružne cilindrične ljuske
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
In this paper the dynamic stiffness method is used for free vibration analysis of a circular cylindrical shell. The dynamic stiffness matrix is formulated on the base of the exact solution for free vibration of a circular ...
Procena čvrstoće betona pri pritisku, korišćenjem različitih funkcija zrelosti betona: primer iz prakse / Assesment of concrete compressive strength using different maturity functions: case study
(Građevinski materijali i konstrukcije, 2018)
Čvrstoća pri pritisku jeste svojstvo koje je veoma značajno u građevinarstvu, te postoji izražena potreba da se razviju metode za praćenje prirasta čvrstoće pri pritisku betona u konstrukciji. Prema zakonskim propisima ...
Validation and implementation of HASP constitutive model for overconsolidated clays / Validacija i implementacija HASP konstitutivnog modela za prekonsolidovane gline
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
There are two important conditions for the wide application of constitutive models for soil in contemporary engineering practice: a) the model should predict sufficiently well the soil behaviour at different stress paths; ...
Flexural buckling of hot-finished and cold-formed elliptical hollow section columns: Numerical comparative analysis / Fleksiono izvijanje naknadno termički obrađenih i hladnooblikovanih stubova elipsastog poprečnog preseka: Numerička uporedna analiza
(Beograd : Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, 2019)
Even though structural elements of the elliptical hollow section (EHS) have been introduced to the construction market in the past years, the rules for their design were only partially introduced into the suitable codified ...
The analysis of application of secondary seismic elements in design according to Eurocode 8 / Analiza primene sekundarnih seizmičkih elemenata u proračunu prema Evrokodu 8
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
Analysis of conceptual design of reinforced concrete (RC) structure with secondary seismic elements in compliance with Eurocode 8 is presented in this paper. The application of this concept is complex due to the requirements ...
Lateral capacity and deformations of vertical piles loaded by horizontal forces / Bočna nosivost i pomeranja vertikalnih šipova opterećenih horizontalnim silama
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
Pile foundations are frequently loaded by horizontal forces. In such cases, it is important to calculate lateral capacity of vertical piles. It is governed by the strength of the surrounding soil i.e. geotechnical capacity ...
