  1. Myield is the yielding moment of the negative loading cycles, and is calculated by the equivalent energy elasto-plastic (EEEP) method [8, 46, 47]; Mu represents ultimate moment of the negative loading cycles; K stands for the bending stiffness, which is equal to the ratio of ultimate moment to ultimate rotation angle
