摘　　要：在大量锈蚀钢筋混凝土梁试验数据的基础上,计算得到不同锈蚀方式和锈蚀率等情况下试验梁的抗弯刚度退化系数,拟合给出钢筋锈蚀率与梁抗弯刚度退化系数的理论计算公式,并通过对新制作的钢筋混凝土试验梁通电加速腐蚀试验,验证计算公式的可靠性和准确性。Based on a large number of test data of corroded reinforced concrete beam,flexural stiffness degradation coefficient about different corrosion methods and corrosion rate are obtained and a theoretical calculation formula of beam flexural stiffness degradation coefficient and rebar corrosion rate is fit.Then the reliability and accuracy of the formula are verified through the new reinforced concrete test beam of accelerated corrosion test.

关 键 词：钢筋锈蚀 钢筋混凝土梁 抗弯刚度 刚度退化系数
