説明

The object of this study is to clarify experimentally and analytically the pullout behavior of axial bars from a footing. The experiments for RC columns subjected to alternate cyclic loadings and the pullout tests for anchorage zone were carried out, and the influences of several factors on slippage of bars have been quantitatively investigated. Furthermore, bondslip model obtained from the results by the finite element method as well as the pullout tests in massive concrete was used in order to evaluate the slippage of bars from the footing. Also, the process of bond mechanism was taken into consideration in order to express the deterioration of bond stress along bars. Calculated values on the basis of proposed method for the evaluation of the slippage of bars have a good agreement with the experimental results.
