［摘要］通过五个单榀陶粒混凝土框架的低周反复加载试验，研究了轴压比、柱纵筋配筋率、柱配箍率对陶粒混凝土框架抗震性能的影响，分析了陶粒混凝土框架的受力全过程、开裂荷载、极限荷载和破坏形态，获得了陶粒混凝土框架的滞回曲线、骨架曲线及其变形能力、耗能能力等抗震性能指标。研究表明，在一定范围内增加轴压比、柱纵筋配筋率和柱配箍率，可提高陶粒混凝土框架抗震性能，且其极限承载力、变形能力、耗能能力均有不同程度的提升。

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
