Abstract
The objective of this study is to clarify the influence of the corrosion form (local corrosion, uniform corrosion) and the corrosion quantity on the bending behavior (bending fracture load, bending stiffness, and deformation behavior) in the reinforced concrete beam. The conclusions in this study are as follows. 1) The yield load, the bending stiffness, the deformation behavior, and the bending fracture load of beam decreased when the corrosion quantity increases regardless of the corrosion form. 2) The bending fracture load decreased to about 50% against the no-corrosion beam, when the weight loss by the corrosion was 60% in the uniform corrosion when the weight loss is 40% in the local corrosion. Also, the bending fracture load is decreased to about 50% against the no-corrosion beam and became rapid destruction, when the local corrosion. 3) The yield load and the bending stiffness are remarkably decreased in serviceability state regardless of the corrosion form, and the deformation increased, when the corrosion quantity was over 30%. 4) The above results 1) were investigated in theoretically as well as in experimentally.
