An Analytical Method for Predicting the Pullout Behavior of Embedded Planar Reinforcements with the Consideration of the Residual Interfacial Shear Strength
https://orcid.org/http://orcid.org/0000-0002-0916-0647
In this paper, an analytical method was proposed to predict the mechanical behavior of embedded planar reinforcements subjected to pullout loads, and a tri-linear shear slip model was employed in the analytical method to consider the residual shear strength at the reinforcement-soil interface. The overall process of the pullout behavior was characterized by five sequential stages. At each stage, closed-form solutions for the distribution of interface shear stress and axial stress along the reinforcement length were obtained as well as the pullout resistance-displacement relationship. On this basis, the analytical model was validated through a comparison with the results of three pullout tests. In conclusion, the pullout resistance-displacement curves and internal displacement distributions predicted by the method agree well with those obtained by the tests.
