| 摘 要： | 通过碳-芳混杂纤维布加固圆木柱(杉木和松木)的轴心抗压性能试验,研究了不同层数的碳-芳混杂纤维布加固圆木柱的破坏形式、轴心抗压强度、峰值压应变和荷载-应变曲线.结果表明:用碳-芳混杂纤维布加固后,圆木柱的轴心抗压强度和峰值压应变有了明显的提高,轴心抗压强度提高幅度约为6.6%～16.8%(松木)和5.0%～16.9%(...

| Abstract: | Based on the experiment of timber circular columns made of deal and fir reinforced by CFRP/ AFRP hybrid FRP(HFRP) sheets under axial compression,the failure modes,axial bearing capacity, peak compression strain and loading-strain curves were investigated.The results show that comparing with the specimens without being reinforced by HFRP,the axial bearing capacity and peak compression strain of the specimens reinforced by HFRP are all improved.The axial bearing capacity of deal specimens is improved by 6.6%-... |
