摘要：

In order to study the performance evalution of reinforced concrete members under earthquake action and establish a reasonable damage model to quantify the damage, based on the damage mechanism of energy dissipation capacity of symmetrical reinforced RC member under variable amplitude hysteretic process, the relationship between the degradation of energy dissipation capacity and design parameters of RC members was studied. On the basis of the estimation method of energy dissipation capacity, the damage quantification index of symmetrical reinforced RC members based on energy dissipation capacity was proposed. Based on the variable amplitude loading test of the existing nine RC members with different reinforcement conditions, the evaluation criteria of damage quantification index of energy dissipation capacity was discussed.It is found that the damage quantification index could provide a unified standard of performance classification for RC members under variable amplitudes. According to the damage quantification index, five performance levels, which are no damage, mild damage, moderate damage, severe damage and failure of RC members, were proposed. The standard was verified by 18 specimens of flexural failure in PEER database with preferably consistency. © 2020, Editorial Office of Journal of Building Structures. All right reserved.
