ABSTRACT
The mechanical properties, damage forms, and deformation characteristics of waste fiber recycled concrete beam-to-column joints under monotonic loadings are studied by numerical simulation. The design variables are the replacement rate of recycled coarse aggregates and the volume fraction of waste fibers. The results indicate that when the replacement rate of recycled aggregates is 50%, incorporating a certain amount of waste fibers can effectively improve the tensile strength of recycled concrete. The ultimate bearing capacity of the beam-to-column is best when the volume fraction of waste fibers is 0.12%.
