In order to study the impact of cast-in-place hollow infill walls with flexible connections of PVC joint plates on the seismic performance of reinforced concrete(RC) frame structures, six full-scale specimens were designed and manufactured with hollow concrete walls and PVC joint plates as the main factors, and pseudo static tests were conducted. By comparing and analyzing the seismic performance indicators such as failure characteristics, load displacement curves, skeleton curves, stiffness, displacement ductility, and energy dissipation capacity of cast-in-place hollow infill wall frame structures with pure frame structures, flexible connections with PVC joint plates, and rigid connections without joint plates, it is mainly concluded that the addition of PVC joint plates reduces the improvement effect of hollow concrete infill walls on the lateral stiffness and bearing capacity of the frame structure. The displacement ductility and energy dissipation capacity of the cast-in-place hollow concrete infill wall frame structure have been improved, providing protection for the infill wall. However, the cast-in-place concrete hollow infill wall with flexible connections using PVC joint plates still significantly affects the lateral stiffness and ultimate deformation of the frame structure. When designing the structure, reasonable consideration should be given to its adverse effects on the overall seismic performance of the structure.
