［摘要］為取代黏土磚多層住宅結(jié)構(gòu)，提出帶斜筋單排配筋混凝土剪力墻多層節(jié)能住宅結(jié)構(gòu)，其抗震性能顯著優(yōu)于磚砌體結(jié)構(gòu)，且與普通混凝土剪力墻結(jié)構(gòu)相比，具有施工簡便、造價(jià)低的特點(diǎn)，便于推廣應(yīng)用。為了解該新型結(jié)構(gòu)體系中T形截面剪力墻的抗震性能，對(duì)1個(gè)單排配筋T形截面混凝土剪力墻和1個(gè)帶斜筋單排配筋T形截面混凝土剪力墻進(jìn)行低周反復(fù)荷載試驗(yàn)，對(duì)比分析其承載力、延性、剛度、滯回特性、耗能能力及破壞特征。試驗(yàn)研究表明，斜筋可以有效限制剪力墻的基底剪切滑移，使得帶斜筋單排配筋T形截面混凝土剪力墻的抗震性能明顯優(yōu)于不帶斜筋單排配筋T形截面混凝土剪力墻，可以更好地滿足多層住宅結(jié)構(gòu)抗震設(shè)計(jì)要求。

Abstract: In order to substitute the clay-brick multi-storey residential structure, the energy-saving multi-storey residential RC shear wall structure with bidirectional single row of steel bars and inclined reinforcements is advised. Its seismic performance is much better than that of the brick masonry structure. It has simpler construction and lower cost compared with ordinary reinforced concrete shear wall structure, and has convenience to be popularized and applied. To study the seismic performance of the new T-shaped shear wall, the low cyclic reversed loading tests of one T-shaped shear wall with bidirectional single row of steel bars and another with bidirectional single row of steel bars and inclined reinforcements were carried out. The comparative analysis of bearing capacity, ductility, stiffness, hysteresis characteristic, energy dissipation capacity and failure characteristics of the two shear walls was made. The results show that the seismic performance of T-shaped shear wall with inclined reinforcements is obviousls better than the wall without inclined reinforcements because the inclined reinforcements can prevent base sliding of the shear wall. The T-shaped shear wall with bidirectional single row of steel borrs and inclined reinforcements can better meet the requirements of seismic design of multi-story residential structure.

Keywords: inclined reinforcement; bidirectional single row of steel bar; T-shaped shear wall; low cyclic reversed loading test; seismic performance
