| 摘 要： | 通过5根CFRP加固钢筋混凝土短圆柱在低周反复荷载作用下的试验,研究了CFRP加固高轴压比钢筋混凝土短圆柱的抗震性能,探讨了CFRP加固用量对试件抗震性能的影响。试验结果表明:CFRP加固高轴压比钢筋混凝土短圆柱能有效提高其抗震性能,使试件从脆性的剪切破坏逐步过渡到有较好延性的弯曲破坏。本文还建议了CFRP加固钢筋混凝土短圆柱抗剪和抗弯承载力计算公式,计算结果与试验值符合较好。

| Abstract: | Five reinforced concrete(RC) circular columns under high-level compression are tested under cyclic loading to investigate the seismic performance of short columns retrofitted with CFRP in this paper.The effects of the amount of CFRP on the seismic behavior of RC short circular columns are studied.Test results show that the failure mode could be changed and the seismic behavior could be reformed effectively for RC short circular columns strengthened with CFRP. New design methods for predicting the shear and flexural capacity of CFRP-wrapped circular RC columns under seismic loading are proposed,and the predicted values are in good agreement with the test results. |
