高强箍筋约束高强混凝土短柱骨架曲线的影响因素

Effecting Factors of Skeleton Curve for High Strength Concrete Column Confined with High-strength Stirrup

以高强箍筋约束高强混凝土短柱试验为基础,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短柱构件骨架曲线的影响。研究结果可为高强箍筋约束高强混凝土构件的应用提供理论基础,并对钢筋混凝土结构的抗震设计提供参考价值。

Based on the experiment on high strength concrete column confined with high-strength stirrup, the influ-ence of stirrup strength and stirrup spacing on skeleton curve of the ordinary strength and high-strength stirrup concrete components during the whole failure process of the components are studied. And the results show that it not only can pro-vide the necessary theoretical basis for application of high-strength stirrup confined concrete, but can give good reference value to the seismic design of reinforced concrete structure.
