o:8500 Selected examples of the application of PAK software for modeling the behaviour of complex engineering structures en The paper presents various examples of the application of the PAK software and its modules for thermal, filtration, and stress–strain analysis of different complex engineering structures such as gravity dams, arch dams, embankment dams, tunnels, and mines. Examples of research, studies, and projects in which PAK has been applied to assess the condition of various structures are provided. Special emphasis is placed on the application of PAK for modeling thermal, filtration, and stress–strain processes at the gravity dam, Iron Gate I Dam, and the arch dam, Grančarevo. PAK has been successfully used for a long time on these structures as part of the Dam Safety Management System, providing the basis for various analyses and reports on the assessment of dam condition and safety. dam, thermal processes, filtration processes, stress-strain processes, PAK 1552101 1820-6530 2025-11-25T10:43:20.708Z 44 no 46 Dejan Divac Jaroslav Černi Water Institute, Belgrade, Serbia 0000-0002-1578-1431 Slobodan Radovanović Jaroslav Černi Water Institute, Belgrade, Serbia person 0000-0002-8437-9016 Maja Pavić Jaroslav Černi Water Institute, Belgrade, Serbia person 0009-0008-6623-0331 Nikola Milivojević Jaroslav Černi Water Institute, Belgrade, Serbia person 0000-0001-5330-1219 Vladimir Milivojević Jaroslav Černi Water Institute, Belgrade, Serbia person 0009-0005-9113 9896 Miroslav Živković University of Kragujevac, Faculty of Engineering, Kragujevac, Serbia person 0000-0002-0752-6289 Dragan Rakić University of Kragujevac, Faculty of Engineering, Kragujevac, Serbia person 0000-0001-5152-5788 application/pdf 968639 https://unilib.phaidrabg.rs/o:8500 no yes 1 70 92000001 71A04 Journal of the Serbian Society for Computational Mechanics 19 1 125 138 Serbian Society for Computational Mechanic 2025
