【摘要】 通过三个自密实轻骨料混凝土框架柱低周往复试验研究,分析不同轴压比对框架柱抗震性能的影响,并与一个普通混凝土框架柱对比分析.试验结果表明:随着轴压比的增加,自密实轻骨料混凝土框架柱的延性逐渐减低,耗散系数逐渐减小;相同轴压比下,普通混凝土框架柱的滞回环更加饱满,耗能能力和延性好于自密实轻骨料混凝土构件.更多还原

【Abstract】 On the basis of experimental results on three self-compacting lightweight aggregate concrete frame columns under low cyclic load,the seismic performance of frame columns in the case of different axial compression ratios is analized and compared with one ordinary frame column.The results indicate that with axial compression increasing,the dissipation coefficient and ductility decrease.Under the same condition of axial compression ratio,hysteresis loop of ordinary concrete frame column is fuller.In contrast to ordinary concrete frame column,the ductility and dissipation factor of self-compacting lightweight aggregate concrete frame columns is lower.更多还原
