The compressive axial force and bending moment act in the same direction, the member experiences a higher level of stress and may be more susceptible to failure. This is because the compressive force increases the stress in the concrete while the bending moment increases the stress in the steel reinforcement.

On the other hand, if the compressive axial force and bending moment act in opposite directions, they can partially cancel each other out, resulting in a lower level of stress in the member. However, this can also lead to a phenomenon called "reverse bending," where the tension side of the member becomes the compression side, potentially leading to failure.

Therefore, it is important to carefully analyze the combined action of compressive axial force and bending moment in reinforced concrete members to ensure their safe and efficient design. This is typically done using structural analysis software or hand calculations based on established design codes and standards.
