A strain compatibility method is based on the strain compatibility approach proposed by AISC (American Institute of Steel Construction, Inc.). The strain compatibility method assumes a linear strain of all the members. After that, set up the equilibrium equations of the state of stress in each component for calculating the location of the neutral axis of the cross-section in the presence. In this study, the reinforced concrete simple beam is analyzed by strain compatibility method for calculating the neutral axis and the bending moment. And then, a variation of neutral axis of the reinforced concrete simple beam is measured.
