在装配式密肋复合墙板低周反复 加载试验的基础上，介绍了密肋复合墙板的破坏形态和裂缝发育，揭示其传力机理及变形规律；并对不同轴压比下 密肋复合墙板的承载能力、刚度、变形、延性、耗能等抗震性能进行了对比分析。
研究结果表明：填充砌块在加载过 形成有利的剪切型破坏模式。
极限荷载之前，密肋复合墙板耗能能力受轴压比大小的影响较小。
面极限荷载之 后，轴压比0.35的墙板具有更好的耗能能力，极限位移和延性系数也较大，具有更好的变形性能和延性。

Seismic performanceof thewalls such asbearing capability，stiffness，deformation capability，dutility and ability of energy dissipation etc. are paratively analyzed under different axial pression ratio. The results show that:filled blocks sustained destruction during the loading process and formed energy dissipation mechanism.Plastic hinge zone appeared in the top of the ribbed-column and “ strong beam weak column” failure mode happened.Filled blocks，wall slabs and outer frames failed in turn，forming a favorable shearing-failure mode. Before ultimate load，the value of axial pression ratio has litle inluence on the energy dissipation capacity ofmulti-ribbed posite walls.Afterultimate load，the wall with axial ...
