摘　　要：通过对14根锈蚀钢筋混凝土简支梁斜截面抗剪性能的试验研究,分析了箍筋和纵筋不同锈蚀程度、剪跨比等因素对斜截面裂缝形成和开展、破坏机理、承载能力等性能的影响,并总结出影响规律,为进一步理论分析提供依据。Fourteen simple supported corroded reinforced concrete beams are tested. The test research of the test consider so many affecting factors as longitudinal steel＇s corrosion rate, stirrups＇ corrosion rate and shear-span rate. The crack process and failure model are observed. The data such as deflection, longitudinal steel strain, stirrups strain and ultimate bear capacity are measured, and the test results are analyzed.
