    Evaluation and modelling of the buckling behaviour of SRC composite columns under simultaneous off-axis and lateral loading by Kabir Sadeghi, Javad Royaei, Fatemeh Nouban

    Published 2025-05-01
    “…Based on the results, it was observed that as the percentage of eccentricity increased (load to lateral load ratio of 0.5), the buckling load of the composite column has decreased. By increasing the eccentricity from 0 % to 100 %, the buckling load reduction rate for the first mode of the column is equal to 3 % and the amount of critical load reduction in this condition is equal to 21 %. …”
