20.500.12556/DKUM-92398 Optimising energy piles: a multi-objective approach to cost and failure probability This paper presents a comparative analysis of the influence of thermal loading on the design of optimally designed floating energy piles in soft consistency soils using a genetic algorithm. The nonlinear settlement of energy piles is also considered. The deterministic optimisation model (OPT-EP) includes a cost objective function constrained by design constraints and is later extended to include the probability of failure as a second objective function to perform multi-objective optimisation. This extension was undertaken because the Eurocode 7 approach only partially accounts for uncertainties in the soil, whereas the reliability-based design (RBD) approach fully exploits these uncertainties. Consequently, a multi-objective optimisation (cost vs. failure probability) was carried out in this study. The optimal designs obtained by the two different optimisation methodologies were further analysed and it was found that when the Eurocode 7 safety factor approach was used, the conditions related to thermal loading were not crucial for the design values. On the other hand, the multi-objective optimisation based on the RBD approach showed that the thermal loading affected the design, proving the usefulness of the multi-objective optimisation and the reliability-based design. energy pile multi-objective optimisation reliability-based design genetic algorithm energetski piloti večciljna optimizacija zasnova zanesljivost genetski algoritmi true false true Taylor & Francis Angleški jezik Slovenski jezik https://www.tandfonline.com/doi/full/10.1080/17499518.2025.2485484#abstract Članek v reviji 2025-04-04 14:36:14 2025-04-04 14:36:15 2025-04-05 03:07:44 0000-00-00 00:00:00 2025 0 0 18 str. iss. 1 Vol. 19 April 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2025-03-23 2025-04-02 624.131:004.021 231505155 10.1080/17499518.2025.2485484 1749-9526 Optimising_energy_piles__a_multi-objective_approach_to_cost_and_failure_probability.pdf Optimising_energy_piles__a_multi-objective_approach_to_cost_and_failure_probability.pdf 1 6C94ACA468AC489013B66F67382C3FAE 468ae555397a0c4f8faf8b3b82e6b0dac2315dd6b30a882ab925eece753dccd7 dd6f2ad1-1151-11f0-b51c-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189994 https://www.tandfonline.com/doi/full/10.1080/17499518.2025.2485484#abstract 0 e40d35df-1151-11f0-b51c-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189995 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
