摘要
紫外线照射对玄武岩纤维布加固钢筋混凝土柱的性能有一定的影响,对不同紫外线照射时间下的16个钢筋混凝土柱进行轴压承载力试验。研究发现,不同层数玄武岩纤维布和不同加固方式下钢筋混凝土柱的极限受压承载力随紫外线照射时间的增长有不同的下降。经过紫外线照射后,玄武岩纤维布加固钢筋混凝土柱的延性降低,对破坏形态没有太大影响。
The ultraviolet rays have effects on characteristics of reinforced concrete column strengthened with BFRP . The compressive behavior of 16 reinforced concrete columns strengthened with BFRP exposed to ultraviolet rays was investigated. The results indicate that ultimate axial compressive strength of the column is decreased when the time of ultraviolet rays irradiation is increased according to lays of BFRP sheet and reinforcement pattern . After ultraviolet rays irradiating ,the ductility of reinforced concrete column strengthened with BFRP is decreased, but it has little influence on failure pattern.
