摘　　要：以弹性理论为基础,建立了锈蚀SRC梁的界面滑移量计算方程式,并进行了求解。讨论了不同荷载作用下,锈蚀SRC梁型钢上下翼缘与混凝土交界面滑移量沿梁长方向的分布特点。对工业厂房型钢混凝土梁耐久性检测结果表明,锈蚀SRC梁的界面滑移量方程式计算结果与工程实际检测结果基本相符,验证了理论研究的正确性,为锈蚀型钢混凝土梁界面粘结滑移本构关系研究奠定了基础。Based on elastic theory, interface slip equations of corroded SRC beam were established and solved. In different loads, the distribution characteristics of bond-slip were discussed between steel flanges and around concrete in long direction along beam. Durability test results of steel reinforced concrete beams shows that the result is the same with SRC beams corroded interface slip. It＇ s verified the correctness of the theoretical study, and the study laid a foundation for bond-slip relation of the corroded SRC beam.
