摘　　要：研究了钢筋混凝土结构时变抗力的多因素影响机制 ,探讨了钢筋、混凝土材料强度的时变衰减规律 ,给出了钢筋混凝土构件的随机时变抗力模型 .考虑结构刚度的时变性 ,提出了时变刚度的简化模型 .并以高层水塔为例 ,根据所提出的强度。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.
