摘　　要：为了研究高强箍筋约束高强混凝土柱的压弯构件性能,以高强箍筋约束高强混凝土压弯构件试验为基础,研究了普通强度与高强箍筋在构件破坏过程中,箍筋强度和箍筋间距对压弯构件骨架曲线的影响。研究结果不仅对高强箍筋约束高强混凝土构件的应用推广提供必要的试验参考,而且可以对钢筋混凝土结构的抗震设计较好的参考价值。In order to study the bending performance of high-strength concrete columns confined by high strength stirrup , the high-strength stirrup confined high strength concrete beam-column test is conchucted .the influence of stirrups and stirrup spacing on skeleton curve with ordinary strength and high -strength stirrup com-ponent during failure process are studied .The research results not only provide the necessary theoretical basis for application of high-strength stirrup confined concrete , but also can give good reference value to the seismic design of reinforced concrete structure .
