In this study, the shear performance of the hollow slab was evaluated through experiments with the web width and volume fraction of steel fiber as variables. The lung pet bottles were used as a hollow materials. The results showed a performance difference of 19.4 to 52.3% depending on the web width, and a mixture of steel fibers showed a higher shear performance of 4.8 to 33.7%.
