摘　　要：对采用高强度钢筋做箍筋的混凝土构件受剪进行了试验研究,试验表明,高强箍筋混凝土构件具有良好的抗震性能,结合推导的钢筋混凝土构件受剪承载力桁架-拱模型计算公式,采用桁架-拱模型计算高强箍筋混凝土,计算结果与试验结果相比较为符合,最后给出了高强箍筋混凝土抗剪计算的实用理论公式。This paper was based on experimental research on shear capacity of concrete members confined with high- strength stirrups. The experimental result indicates that concrete members with high-strength stirrups have good seismic performances. The truss-arch model derived in this paper was used to calculate the shear capacity of concrete members confined with high-strength stirrups. The calculation results were comparable with the experimental results, and shear calculation formula of the practical theory for concrete members confined with high-strength stirrups was proposed in this paper.
