20.500.12556/DKUM-92026 Full-scale test and load-bearing capacity evaluation of synthetic-polymer-fiber-reinforced concrete tetrapods under quasi-static loading This paper studies the load-bearing capacity of various concrete tetrapods under quasistatic loading. The tetrapods were made of plain concrete and synthetic-polymer-fiber-reinforced concrete. Load tests of the tetrapods were performed. The maximum load-bearing capacity and the residual-load-bearing capacity of the tetrapods (the load-bearing capacity after the first crack or at different crack widths) were evaluated. The strength and residual-strength values were backcalculated from the load-bearing capacities, and compared with available data from the literature. The specimens with and without fibers achieved similar maximum load-bearing capacities, with cracks occurring at identical locations. However, the differences in residual-load-bearing capacity were more significant. The synthetic-polymer-fiber-reinforced concrete tetrapods exhibited relatively high residual-load-bearing capacities, even at higher displacements and crack widths. Two different calculation-procedures were used for the load-bearing-capacity evaluation. A load-displacement calculation based on the moment-versus-curvature relation and the plastic-hinge approach was performed, and additionally proved the applicability of the employed calculation-procedures for the concrete tetrapod load-bearing-capacity evaluation. tetrapods concrete synthetic-polymer fibers load tests load-bearing capacity residual load-bearing capacity load displacement calculation gradbeno inženirstvo tetrapodi beton sintetična polimerna vlakna obremenitveni testi nosilnost residualna nosilnost premik bremena izračun true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/buildings © 2022 by the authors Članek v reviji 2025-03-12 08:04:34 2025-03-12 08:04:35 2025-03-13 03:12:44 0000-00-00 00:00:00 2022 0 0 str. 1-21 iss. 12 Vol. 12 Nov. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-11-15 2022-11-30 2022-12-05 691:625.843 133529091 10.3390/buildings12122143 2075-5309 buildings-12-02143-v2.pdf buildings-12-02143-v2.pdf 1 BAA3AC06BFACD0A59E5B1539419958CD cd6784c2d15a546829655b86a76eefa5f27ff9bc88dbc967097b9c0552329af7 a35eba30-ff10-11ef-9eb9-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189192 https://www.mdpi.com/2075-5309/12/12/2143 0 ad856e10-ff10-11ef-9eb9-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189193 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
