摘要(Abstract):

通过 6根配置LL5 5 0冷轧带肋箍筋的高强混凝土柱的抗震性能试验 ,研究了LL5 5 0冷轧带肋箍筋高强混凝土柱在不同轴压比和水平往复荷载作用下的破坏规律 ,以及轴压比、箍筋间距和纵向钢筋配筋率等对压弯构件延性的影响。综合已有高强混凝土压弯构件的试验资料 ,给出了配LL5 5 0冷轧带肋箍筋高强混凝土柱抗震设计中最小含箍特征值限值的建议。
This paper presents an experimental study on 6 HSC columns with Grade 550 cold rolled ribbed steel stirrups under constant axial loading and cyclic lateral loading.The failure mode of the columns was investigated.And it was proved that main variables such as the axial load ratio,the stirrups spacing and the longitudinal reinforcement ratio had great effects on the ductility of HSC columns.The minimum stirrups requirements for different antiseismic design grade were proposed.
