针对BFRP筋混凝土结构受弯时出现裂缝较大的特点,在BFRP筋混凝土梁中加入短切玄武岩纤维,探究了其裂缝的改善情况,并完成了3种纤维体积掺量和3种配筋率下的BFRP筋纤维混凝土梁的抗弯试验,得出了玄武岩纤维体积掺量和配筋率对BFRP筋纤维混凝土梁裂缝的影响规律。
Aiming at the large cracks in BFRP reinforced concrete structures during bending, the chopped basalt fibers were added into the BFRP reinforced concrete beams to investigate the improvement of cracks. Three kinds of fiber volume contents and three kinds of reinforcement ratio Under the bending test of BFRP tendon-fiber reinforced concrete beam, the influence of basalt fiber volume content and reinforcement ratio on the crack of BFRP tendons fiber reinforced concrete beam was obtained.
