Experimental Study on Shear Capacity of Waste Fiber Recycled Concrete Shear Wall

In this paper, the shear capacity of waste fiber recycled concrete shear wall (FCSW) is studied by cyclic loading tests on 9 specimens. The failure of the specimens under low cycle cyclic loading is analyzed. The influence of waste fiber content, recycled aggregate content and axial compression ratio on the shear capacity of shear wall is studied. The results show that: the larger the volume ratio of waste fiber is, the higher the shear bearing capacity of shear wall is; the addition of recycled coarse aggregate will reduce the shear capacity of shear wall; the shear capacity of shear wall increases with the increase of axial pressure. On the basis of relevant specifications, the calculation formula of in-plane shear capacity of waste fiber recycled concrete shear wall is proposed considering the influence of waste fiber on shear capacity. By comparing with the test results, it can be found that the two formulas are in good agreement. The conclusion of the study can provide reference for the design of waste fiber recycled concrete shear wall.
