Abstract:A study was conducted on the seismic performance of five single ceramsite concrete frames under low reversed cyclic lateral loading. The influence of axial compression ratio,  column longitudinal reinforcement ratio and  column stirrup ratio on the seismic performance of the ceramic concrete frame were carried out. The force process, cracking load, ultimate load and failure mode of the ceramsite concrete frame were analyzed. The hysteresis loops, skeleton curve, deformation capacity and energy dissipation of the ceramsite concrete frame were obtained. The research shows that the increasing of axial compression ratio, longitudinal reinforcement ratio and column stirrup ratio can obtain effective performance improvement on the limit bearing capacity, deformation capacity, energy dissipation capacity and seismic performance of ceramsite concrete frame.

Keywords:ceramsite concrete frame; seismic behavior; longitudinal reinforcement ratio; stirrup spacing; axial compression ratio
