Influence of Loading Sequence on Low Cycle Fatigue Behavior of Normal Weight Concrete under Direct Tension

CODEN: JTEVAB

Abstract

Under seismic action, concrete can be considered to be subjected to multistage constant cyclic loads. Moreover, the failure of concrete is predominantly manifested in cracking caused by tension. This article studies the dynamic mechanical properties of concrete specimens under direct cyclic tension. According to the experimental results, this article discusses selections of damage parameters and the establishment of the evolution model on the basis of elastic modulus degradation and plastic strain accumulation. According to reasonable damage parameters, the damage evolution mechanism is investigated to propose a modified model, by which the failure process and the fatigue life of concrete under cyclic loading can be predicted. Additionally, the proposed damage evolution model is used to analyze the experimental data of the related literature and this study, which both turn out a good match in the prediction.
