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。
Ultraviolet radiation has certain influence on the performance of reinforced concrete columns reinforced with basalt fiber cloth. The axial compression bearing capacity of 16 reinforced concrete columns subjected to different ultraviolet irradiation time is tested. The study found that the ultimate compression bearing capacity of reinforced concrete columns with different layers of basalt fiber cloth and different reinforcement methods decreased with the increase of UV irradiation time. After UV irradiation, basalt fiber reinforced concrete columns to reduce the ductility of the destruction of morphology is not much impact.
