Abstract
In order to study the influence of bamboo fiber and steel wire mesh on the flexural ductility of Basalt Fiber Reinforced Polymer（BFRP）bars concrete beams, seven BFRP bars concrete beams reinforced with bamboo fiber and steel wire mesh were tested with the bamboo fiber length (0mm, 30mm, 45mm) and the steel wire mesh layout range (none, 1/2 maximum bending moment point layout, full beam segment layout) as variables. The flexural failure test of 7 basalt fiber reinforced concrete beams reinforced by bamboo fiber and steel wire mesh was carried out, and the initial crack load, crack development, ultimate load and deformation were detected. The effects of fiber length and layout range of wire mesh on the crack resistance and deformation resistance of specimens are analyzed by the test data. With the help of functional model, the equivalent yield points of the seven test beams were obtained, and the ductility coefficients of the specimens were calculated. The results show that the addition of bamboo fiber and steel wire mesh increases the cracking load of BFRP bars concrete beams by 12% ~ 68%, reduces the crack distribution spacing and length development speed, reduces the deformation of test beams under the same load, and increases the ductility coefficient by 1.58% ~ 31.75%.
