This study presents a comparative capacity analysis of RC bridge columns based on the Albanian code, Eurocode 2, and AASHTO LRFD. Ultimate axial force and bending moment capacities are calculated analytically using selected overstrength parameters, and representative case studies illustrate how normative differences influence column design and seismic performance. 12 31 2025 12 31 2025 217 24 https://creativecommons.org/licenses/by/4.0/deed.en_US 10.37394/232011.2025.20.24 https://wseas.com/journals/mechanics/2025/a485111-600.pdf Turchetti.
