Abstract

Corrosion of Lap spliced region causes the Bond strength to change. The ratio of the Bond strength in the corrotion state to the value of its corresponding in the absence of Corrosion is called the relative Bond strength. The results of the relative Bond strength are different in Pullout test, Tension stiffening test and Beams with Lap spliced bars test. The results of theTension stiffening test in the literature is more similar to those of Beams with Lap spliced bars. In this study, a model has been proposed using tension stiffening tests, for determining the relative Bond strength of corroded steel bars in the descending branch. Finally, this model has been optimized using genetic algorithm for determining the relative Bond strength of RC Beam with corroded Lap spliced steel bars. The current study shows that using the proposed model will lead to the beter result. The use of proposed model for the estimating the relative Bond strength of RC beam with corroded Lap spliced steel bars, leads to about 16 percent reduction in total error compared with Shihata model.
