Abstract: According to a discussion on the vertical loading and creep,it was elaborated the effect of vertical deformation difference of a structure on internal force redistribution,it was analysed the differences between the different vertical loadings,applicable scope and matters needing attention. It was analyzed the differences between the creep deformation and forced-deformation and thier impact on structural and non-structural components. The combined consideration on the force,calculation the structure of selection,material selection and structural measures was the countermeasure to solve the vertical deformations difference.
