玄武岩纤维钢筋混凝土梁弯曲性能试验研究
Experimental Study on Flexural Behavior of Basalt Fiber Reinforced Concrete Beams
摘要
Abstract
Through the four point bending test of basalt fiber reinforced concrete beams ,analysis of their failure patterns and mechanisms . And study on the variation law of bearing capacity , deflection , toughness , concrete strain and steel strain of the beam with different basalt fiber content .Test results show that:basalt fiber reinforced concrete beam on the cracking load and ultimate load is enhanced , the maximum amplitude of the cracking load is 32%, and the maximum amplitude is 6 .5%.The deflection , ductility and toughness of basalt fiber reinforced concrete beams are better than that of ordinary reinforced concrete beams . The compressed concrete beam of basalt fiber has the ability to prevent crack propagation , when the upper compression zone of crushed concrete beam , concrete pieces will not peel in bridging fibers , the beam still maintain good integrity .关键词
