...Lu Li; Dong-hua Zhou; Chao Shuang; Chunxiu Han; Shuwei Lan Purpose To calculate the bearing capacity of annular reinforced concrete (RC) columns, if the second-order effects of members under bending and axial forces are further considered, both the nominal curvature method and the nominal...

.... Originality/value Calculating the bearing capacity of compression bending components requires considering second-order effects. Therefore, the calculation of the bearing capacity of circular RC columns requires iterative calculation, as it includes dual nonlinearity of material and geometry, and the two...
