摘要
To study the hysteresis model of reinforced concrete (RC) columns strengthened by textile reinforced concrete (TRC), eleven RC columns were designed and ten of them were strengthened with TRC, and then all of them were carried on the low cyclic loading test.According to the experimental results, the degradation three linear skeleton curve model is suitable with considering the factors of textile layers (N) and axial compression ratio (n0).The skeleton curve model of RC column strengthened with TRC was established though calculating parameters of skeleton curve with the method of linear regression using the Origin software.Then based on the skeleton curve model, the hysteresis model of RC columns was obtained by simplifying the hysteresis rules.The results shows that the proposed hysteresis model could better reflect the hysteretic behavior of TRC-strengthened columns.In addition, this would provide the theoretical basis for the seismic response analysis and seismic reliability evaluation of TRC-strengthened RC structures, which is of great significance to the engineering application for TRC. © 2019, The Editorial Board of Journal of Basic Science and Engineering.
