摘要
通过对3个套筒灌浆连接和3个螺栓连接的预制混凝土柱在低周反复荷载作用下的试验研究,对比分析了两种连接方式在不同轴压比作用下的破坏形态、破坏模式、试验曲线、连接构造对抗震性能的影响。结果表明:轴压力的作用能够有效增强试件的耗能能力,套筒灌浆连接试件与螺栓连接试件的承载力相当,加载后期其刚度退化速率更小,位移延性更好。
The experimental study of three grout sleeve splicing specimens and three bolt connection specimens under low cyclic reversed loading has been chose to analysis the failure patterns,failure modes,curves,connections influence to seismic behavior of these two connections under different axial compression ratio. It＇s shows that the axial pressure can effectively enhance the energy dissipation capacity of specimens,the bearing capacity of these two connections are relatively close,but the stiffness degradation rate in the later loading stage of grout sleeve splicing specimens is smaller and its displacement ductility is better than bolt connection specimens.
