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

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。

Experimental study on seismic behavior of high performance concrete shear wall with high reinforcement ratio boundary elements

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,rigidity degeneration and energy dissipation etc.were...
