Experimental Study on Prestress Loss of Concrete Beam Under Fatigue Loading
To understand the prestress loss of prestressed concrete beam under fatigue loading, several post-tension cohesive prestress concrete test model beams were made on the basis of similar theoretic design, the concrete strain, reinforcement stress, and the stress state of prestressed reinforcement were analyzed through the constant-amplitude fatigue test, and the experimental study of the prestress loss was carried out under fatigue loading. The experimental results indicated that the fatigue loading effect has small degree of injury to non-split beam; the prestress loss existed in the prestressed concrete beam under fatigue loading and in three stages in the whole loading process basically, and that the remaining carrying capacity of the prestressed concrete beam has almost no change but increased to a certain extent.
