Based on the age-adjusted elastic modulus method of concrete linear creep theory, the static and finite element methods for the analysis of the creep stability of reinforced concrete pressure rods are discussed. The stability analysis of this kind of compression rods is derived through the virtual work equations. The unit stiffness equation was calculated using the corresponding program developed.
