［摘要］為研究鋼管混凝土邊框帶斜筋柱式配筋剪力墻的地震損傷規(guī)律，設(shè)計(jì)、制作了4片不同構(gòu)造形式的剪力墻試件，進(jìn)行了低周反復(fù)加載試驗(yàn)，并分析了試件地震損傷演化過(guò)程；對(duì)各試件進(jìn)行基于能量法的地震損傷分析，研究了鋼管混凝土邊框和帶斜筋柱式配筋形式對(duì)試件地震損傷的影響。結(jié)果表明：鋼管混凝土邊框和帶斜筋柱式配筋的構(gòu)造組合顯著減小了試件地震損傷指數(shù)，提高了試件抗震性能，其中柱式配筋形式可以大幅提高試件延性性能，斜筋能夠加強(qiáng)試件抗側(cè)剛度，鋼管混凝土邊框在加載后期可以為試件提供良好的承載力、剛度和變形儲(chǔ)備；所建立的地震損傷評(píng)定模型，較好地體現(xiàn)了鋼管混凝土邊框帶斜筋柱式配筋剪力墻損傷指數(shù)與試驗(yàn)損傷形態(tài)之間的關(guān)系。

Abstract:In order to study the seismic damage of shear wall of concrete-filled steel tube boundary and column-type reinforcement with oblique steel bars, four pieces of shear wall specimens with different structures were designed and manufactured, and the low cycle reversed load experiment was performed and seismic damage evolution process were analyzed. Seismic damage analysis was performed with the method of energy, and the mechanism of the seismic damage of  concrete-filled steel tube boundary and column-type reinforcement with oblique steel bars were studied. The results show that the combination of the  concrete-filled steel tube boundary and column-type reinforcement with oblique steel bars have significantly improve the seismic performance of the specimens, the form of column reinforcement could greatly improve the ductility performance of the specimens, the oblique steel bars can strengthen the lateral stiffness of the specimens, the concrete-filled steel tube boundary can provide good load-bearing, stiffness and deformation capacity for the specimen in the later stage of loading. The seismic damage assessment model can well reflect the relationship between the damage index and the experimental damage pattern of shear wall of concrete-filled steel tube boundary and column-type reinforcement with oblique steel bars.

Keywords:shear wall; seismic damage; concrete-filled steel tube boundary; column-type reinforcement; oblique steel bar
