o:1675 Stability analysis of concrete arch dam using finite element method en Abstract: This paper presents the procedure of numerical stability analysis of a concrete arch dam using the finite element method. Based on the geometry of the dam and the associated rock mass, an optimal finite element mesh of the model was created. Boundary conditions and loads were set so that they correspond to the real conditions of exploitation of the dam. The rock mass is divided into five quasi-homogeneous zones in accordance with the geological maps obtained from the field survey. The mechanical behavior of the dam model and the surrounding rock mass is described using the Hoek-Brown material model. The parameters of the material model were obtained through the identification process using experimental tests of soil samples at the site and in the vicinity of the structure. Numerical simulations of filtration, thermal and stressdeformation processes at the dam are performed using PAK software. In the presented analysis, the control of the permissible compressive and tensile stresses is performed according to the USBR recommendations, where the distance between the actual stress and the permissible stress in the concrete is shown. The global safety factor of the dam is determined using the shear strength reduction method. concrete arch dam, finite element method, Hoek-Brown material model, PAK, stability analysis 2023-04-13T07:08:21.570Z 44 no 46 Dragan Rakić Fakulteta inženjerskih nauka Univerziteta u Kragujevcu ; Faculty of Engineering University of Kragujevac Miroslav Živković Fakulteta inženjerskih nauka Univerziteta u Kragujevcu ; Faculty of Engineering University of Kragujevac person Milan Bojović Fakulteta inženjerskih nauka Univerziteta u Kragujevcu ; Faculty of Engineering University of Kragujevac person Slobodan Radovanović Institut za vodoprivredu "Jaroslav Černi" ; Jaroslav Černi Water Institute person 0000-0002-8437-9016 Aleksandar Bodić Fakulteta inženjerskih nauka Univerziteta u Kragujevcu ; Faculty of Engineering University of Kragujevac person Nikola Milivojević Institut za vodoprivredu "Jaroslav Černi" ; Jaroslav Černi Water Institute person 0000-0001-5330-1219 Dejan Divac Institut za vodoprivredu "Jaroslav Černi" ; Jaroslav Černi Water Institute person 0000-0002-1578-1431 application/pdf 738880 https://unilib.phaidrabg.rs/o:1675 no yes 1 70 92000004 71A04 6th International Scientific Conference on Mechanical Engineering Technologies and Applications “COMETa 2022”, 17-19 November 2022, Jahorina, Republic of Srpska, Bosnia and Herzegovina 301 308 Faculty of Mechanical Engineering, University of East Sarajevo 2022
