This paper analyzes the various calculations of reinforced concrete eccentric compression members. A cubic equation for solving the relative height of the neutral axis is deduced for a small eccentric compression member. This paper proposes that the cubic equation reduced by the partitioned reduction order approach is reduced to an equation. This simplifies the calculation of reinforcement for small eccentric compression members.
