Abstract

Abstract

Based on the freeze-thawing and fatigue alternate experiment of twelve prestressed concrete beams, the effects of fatigue load limit, strength grade of concrete, prestress degree and freeze-thaw fatigue alternating frequency ratio on the variation of specimens appearance, deflection under fatigue load and concrete dynamic elastic modulus of specimens were studied.The effects of prestress degree, fatigue load limit and freeze-thaw fatigue alternating frequency ratio on the attenuation rate of dynamic modulus of elasticity were also studied by using the range analysis method.Test results show that applying prestress and improving the strength of concrete can effectively improve the frost resistance of concrete;freeze-thawing can promote the increment of mid-span deflection and attenuate the stiffness of specimens under fatigue load.The fatigue load limit is always the control factor which affect the dynamic modulus of elasticity attenuation, and the influence of factors that prestress degree and freeze-thaw fatigue alternating frequency ratio gradually go strong with the experiment on the damage of specimens.
