This paper presents the stress-strain analysis of terrain using the finite element method in the settlement Medaković in Belgrade during the construction and occupation of the eighth floor residential building. The slope ...
Nonlinear stability analysis of the frame structures / Nelinearna analiza stabilnosti okvirnih nosača
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
In this paper the phenomenon of instability of frames in elasto-plastic domain was investigated. Numerical analysis was performed by the finite element method. Stiffness matrices were derived using the trigonometric shape ...
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 ...
Fiber finite element in nonlinear analysis of square CFT columns / Fiber konačni element u nelinearnoj analizi kvadratnih spregnutih CFT stubova
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
The paper presents nonlinear analysis of square CFT columns using distributed plasticity fiber elements. Behaviour of CFT columns is nonlinear and it is necessary to include different nonlinear effects into the numerical ...
Redistribution effects in linear elastic analyses of continuous composite steel-concrete beams according to Eurocode 4 / Redistribucija uticaja u linearno elastičnoj analizi spregnutih kontinualnih nosača od čelika i betona prema Evrokodu 4
(Univerzitet u Nišu, Niš, 2011)
Different analytical methods, with different levels of approximations and accuracy, are available for analysis of continuous composite steel-concrete beams. The Eurocode 4 recommends few simple methods for calculation of ...
Strengthening of timber beams using FRP bars / Ojačanje drvenih greda primenom FRP šipki
