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.Keywords: reinforced concrete; durability; seismic; damage parameter*國家自然科學(xué)基金項目（51178470）。作者簡介：梁巖，博士研究生，Email：lyfeel555@163.com。參考文獻［1］LEEA H S，KAGET,NOGUCHI T, et al.An experimental study on the retrofitting effects of reinforced concrete columns damaged by rebar corrosion strengthened with carbon fiber sheets［J］.Cement and Concrete Research,2003,33(4):563-570.［2］貢金鑫，仲偉秋，趙國藩.受腐蝕鋼筋混凝土偏心受壓構(gòu)件低周反復(fù)性能的試驗研究［J］.建筑結(jié)構(gòu)學(xué)報，2004，25(5)：92-97.［3］牛荻濤，陳新孝，王學(xué)民.銹蝕鋼筋混凝土壓彎構(gòu)件抗震性能試驗研究［J］.建筑結(jié)構(gòu)，2004，34(10)：36-38.［4］HAKAN YALCINER,SERHAN SENSOY,OZGUR EREN.Time-dependent seismic performance assessment of a single degree of freedom frame subject to corrosion［J］.Engineering Failure Analysis,2012,19(11)：109-122.［5］惠云玲,李榮,林志伸,等.混凝土基本構(gòu)件鋼筋銹蝕前后性能試驗研究［J］.工業(yè)建筑，1997，27(6)：14-18.［6］吳勝興. 鋼筋混凝土結(jié)構(gòu)銹蝕損傷研究綜述［J］.工程力學(xué)，2002,22（S1）:70-88.［7］張喜德，韋樹英，彭修寧.鋼筋銹蝕對混凝土抗壓強度影響的試驗研究［J］.工業(yè)建筑，2003，33(3):5-7.［8］GB 50010—2010 混凝土結(jié)構(gòu)設(shè)計規(guī)范［S］. 北京: 中國建筑工業(yè)出版社，2011.［9］DAGHER H J，KULENDRAN S.
