| 摘 要： | 通过对九根高强混凝土柱在低周反复荷载作用下受力性能的试验研究，探讨了碳纤维布对高强混凝土柱延性的改善作用，包括加固后柱的破坏形态、滞回曲线、骨架曲线、延性系数等性能特点。试验结果表明，采用碳纤维布横向缠绕高强混凝土柱可显著提高柱的延性，改善柱的抗震性能。

| Abstract: | Nine high-strength reinforced concrete columns were tested under cyclic lateral load and constant axial load. The effectiveness of the high-strength reinforced concrete columns strengthened by the CFRP for enhancing its ductility and earthquake-resistance is described. Failure pattern, hysteresis curves, skeleton curves and displacement ductility of the columns are studied systematically in tests. The experiment results show that the ductility of the columns is obviously increased, and seismic behavior is improved. |
