| 摘 要： | 对无粘结预应力混合装配式联肢墙中普通钢筋与预应力筋的布置及其面积比对抗震性能的影响进行了研究,给出了合理的设计建议。对无粘结预应力混合装配式联肢墙和直接装配式联肢墙进行了对比试验研究,结果表明无粘结预应力装配式联肢墙具有"自恢复"的性能,卸载后残余变形小,非线性变形集中于连接区域,震后易修复,与直接装配式联肢墙相比,具有较好的耗能能力和较高的承载力。

| Abstract: | The effect of the arrangement of bar reinforcement and unbonded post-tensioned reinforcement and ratio of area of bar reinforcement to unbonded post-tensioned reinforcement on seismic behavior of hybrid reinforced precast coupled wall are analyzed,then appropriate design suggestions are proposed.Two specimens of unbonded post-tensioned precast coupled wall were tested,one was the hybrid precast coupled wall and the other was the direct precast coupled wall for comparison.The results validated that unbonded ... |
