    In terms of the flexural stiffness of reinforced concrete beams, which of the following statements is wrong.
    A: The bending stiffness of reinforced concrete beam varies in the process of loading
    B: The short-term bending stiffness of reinforced concrete beams is derived from the curvature relation of cross-section
    C: The short-term average bending stiffness is adopted in the deflection checking calculation
    D: The bending stiffness under long-term load is smaller than that under short-term load
