摘要

摘要: 提出一种新型预应力预制混合装配短肢墙(PPHSW)，以有限元软件DRAIN-2DX为分析平台，编制相应的程序对其进行建模及分析。首先研究张拉预应力筋在连梁中建立轴压力的情况，再对结构进行静力弹塑性分析。结果表明，张拉顺序对连梁中最终建立的轴压力的大小无影响;受墙肢底部固端约束，预应力筋张拉后传递到1层连梁的轴力值较小，固端约束效应在1层以上迅速衰减;结构具有良好的受力性能，延性较好，侧移曲线为弯剪形。为尽可能延迟连梁预应力筋屈服状态，在加载过程中，结构的耦联率基本保持不变，耦联率不宜过大。

Abstract: In this paper,a new kind of prestressed precast hybrid coupled wall(PPHSW) was proposed.Study was carried out with a computer program developed based on th finite element DRAIN-2DX.The results indicated that tension order has nothing to do with the axial force in coupling beams,but the value is less in the frist story coupling beam because of the fixed end in the bottom of the pier,the restraint effect of the fixed end is decayed quickly.Structure has good earthquake resistant behavior,with lateral displacement curve of shear-flexural type,in order to delay the state of yielding of prestressed tendons in coupling beams as much as posssible;throughout the process of loading the degree of coupling basically unchanged,the value should not be too large.
