[提要] 通過10根銹蝕鋼筋混凝土壓彎構(gòu)件在低周反復(fù)荷載作用下的試驗研究,分析了經(jīng)過自然暴露、快速電腐蝕后,再經(jīng)氯離子干濕交替環(huán)境下的銹蝕鋼筋混凝土壓彎構(gòu)件在不同軸壓比下的破壞規(guī)律,討論了鋼筋銹蝕量對試件承載力、剛度、延性及耗能能力等抗震性能的影響,并與以往的試驗結(jié)果進行了對比。試驗表明,鋼筋的銹蝕量和構(gòu)件的軸壓比是影響銹蝕鋼筋混凝土壓彎構(gòu)件抗震性能的主要因素。
[關(guān)鍵詞] 鋼筋混凝土壓彎構(gòu)件 鋼筋銹蝕抗震性能Based on the test results of ten RC members under low cycle reversed loads,which are corroded by exposing in natural environment,accelerated electrochemical method, and alternating drying-wetting in chloride case, the damaging rules of members under different axial compressive loads are studied. The influences of corrosive amount on the seismic behavior,such as bearing capacity, stiffness, ductility and energy dissipation,are discussed.
