英文摘要：

Based on the available experimental data and theoretical analysis, the influence factors on seismic analysis of reinforced concrete structure with durability damage were mainly discussed, including section geometrical damage, the performance deterioration of concrete and steel, the reduction of bond-slip of reinforced concrete. The concept and calculation method of damage parameters of reinforced concrete structure seismic durability were presented. Based on the existing restoring force model of reinforced concrete structure, and considering the damage parameters of various seismic durability, the skeleton curves of the corroded members can be got. These curves generally are in good agreement with the existing experimental data, which means these damage parameters can be used in seismic response analysis of damage reinforced concrete structure.
