摘要:
为了研究钢框架双钢板内填混凝土剪力墙结构(SFSCSW)的滞回性能,设计了单跨2层半、缩尺比为1:3的SFSCSW试件,并对试件进行了的低周反复加载试验,研究了试件在循环荷载作用下的破坏模式、变形能力、耗能能力,得到了试件的滞回曲线、骨架曲线、刚度退化曲线、承载力降低系数曲线、延性系数等。试验结果表明:钢框架双钢板内填混凝土剪力墙结构承载能力高、抗侧刚度大,具有较好的延性和较强的耗能能力;在水平荷载作用下,剪力墙底部墙角外鼓,柱脚翼缘部分屈曲,剪力墙结构发生压弯破坏;钢框架双钢板内填混凝土剪力墙试件1层的层间刚度比2层大,侧向变形比2层小;钢框架双钢板内填混凝土剪力墙结构刚度退化平缓,同一位移加载,承载能力减小程度有限;钢框架双钢板内填混凝土剪力墙结构试件的剪切变形较小。
Abstract:
To research hysteretic?behavior of steel frame with steel-concrete-steel composite shear walls (SFSCSW), the one-bay two and a half story specimen at one-third scale was carried out under low reversed cyclic loading. The failure modes, deformation pe rformance and energy-dissipation of specimen were observed. Valuable results were obtained for hysteretic loops, skeleton curves, rigidity degeneration, load drop curves and ductility coefficient. Experimental studies and analysis show that SFSCSW could provide well ductility, High bearing capacity and lateral stiffness ,demonstrate excellent deformation performance and energy-dissipation capacity. The bottom of the shear wall corner exist outside surface deformation, column base f lange buckling and shear walls were compression-flexure failure under horizontal load. The first floor deformation is smaller than second floor and has larger?interlayer stiffness relative to second floor. The SFSCSW stiffness degradation were slowly. Afte r Specimen entering the plastic, at same displacement loading, the bearing capacity of the specimen to reduce is very small and the shear deformation of shear walls were small.
