Evaluation of Residual Axial Load-Carrying Capacity of RC Shear-Damaged Columns
Abstract eng: In this paper, an arch resistance model, which can be applied to the evaluation of residual axial load carrying capacity of Reinforced Concrete (RC) columns with shear damage, is proposed based on the theory of mechanics. The proposed arch resistance model can give a better understanding of the loss of axial load carrying capacity of shear-damaged RC columns. The evaluation formula of residual axial load carrying capacity of RC column, which consists of contributions by longitudinal reinforcement and core concrete, is derived based on the proposed arch resistance model. In addition, to verify the accuracy of the formula proposed in this paper, a database of RC columns experimentally damaged in shear is compiled and estimation results obtained by the proposed formula are compared with experimental results. The results obtained by the proposed formula shows a good agreement with the compiled experimental results.
