高配筋率边缘约束构件高强混凝土剪力墙抗震性能试验研究OA北大核心CSCDCSTPCD
Experimental study on seismic behavior of high performance concrete shear wall with high reinforcement ratio boundary elements
为改善高强混凝土剪力墙的延性,设计了7个不同形式的高配筋率边缘约束构件高强混凝土剪力墙试件（边缘约束构件内的纵筋配筋率约为5%～8%）和1个普通配筋率的高强混凝土剪力墙试件,对其进行低周反复水平荷载作用下的拟静力试验,研究了剪力墙试件的破坏形态、滞回特性、变形能力、截面应变、刚度退化、耗能能力等。试验结果表明：对于剪跨比λ≥2的剪力墙,在高强混凝土剪力墙中设置高配筋率暗柱或端柱,并适当提高水平和竖向分布钢筋的配筋率,可以显著提高高强混凝土剪力墙的抗震性能。
To improve the ductility of high strength concrete shear wall,seven specimens of the HPCSW with high reinforcement ratio boundary elements（the longitudinal reinforcement ratio of the boundary element is set to be 5%~8%） and one specimen of the HPCSW with ordinary reinforcement ratio boundary element were designed and tested under low cyclic reversed lateral loading.Seismic behavior such as failure pattern,hysteretic characteristics,displacement ductility,rig…查看全部>>
