【Abstract】 In this paper the multi factor effect mechanics of resistance on reinforced concrete is studied based on the time dependent property.The laws of time dependent growing weak on the materials’ strength of reinforcing bar and concrete are discussed.The model of the random time dependent resistance on reinforced concrete structure is given.The simplified structural stiffness model is put forward,which considers the characteristics of time dependent structural stiffness,including short term and long term structural stiffness.As an example,it has analyzed time dependent resistance of the component parts of a tall tower structure based on the model mentioned above.更多还原
