轴压比对土坯墙片抗震性能的影响

Influence of axial compression ratio on seismic performanceof adobe wall

为进一步研究轴压比对土坯墙片承载力及延性的影响规律,通过已知试验验证有限元模型的可靠性,分别对不同轴压比下土坯墙片进行拟静力数值模拟.分析结果表明,轴压比界于0.1~0.3之间,墙体呈现"X"破坏模式,且有较好的承载力及延性,随着轴压比的增大,呈现出斜压破坏趋势,承载力及延性逐渐降低.

In order to further study the influence of axial compression ratio on the bearing capacity and ductility of adobe wall,the reliability of the finite element model is verified by known tests,and the quasi-static numerical simulation of adobe wall under different axial compression ratio is carried out.The results show that the axial compression ratio is in the range of 0.1~0.3,the wall presents an"X"failure mode,and has good bearing capacity and ductility.With the increase of the axial compression ratio,the wall presents a inclined compression failure trend,and the bearing capacity and ductility decrease gradually.
