Abstract
In this chapter, the studies on the seismic performance of recycled aggregate concrete (RAC) columns and confined RAC columns are performed. The main parameters in these studies are recycled coarse aggregate (RCA) replacement percentage, construction sequence, bond–slip effect, and confinement. Based on these investigations, failure pattern, hysteresis curves, skeleton curves, energy dissipation, and stiffness deterioration laws of RAC columns and confined RAC columns are analyzed. The RCA effect on seismic performance of columns is significant. The construction sequence can also affect the seismic behavior of columns. It was discovered that the confinement obviously improved the seismic performance of RAC columns.
