摘　　要：普通配筋的高强混凝土构件抗剪性能较差,脆性性质明显.配置高强箍筋能改善高强混凝土梁的抗剪性能,减小脆性性质.通过6根配有高强箍筋的简支梁试验,研究高强箍筋高强混凝土梁的抗剪性能,以及各种因素对构件抗剪性能的影响.试验中使用极限强度为800N/mm2和1 100N/mm2的箍筋,结果证实合理配置高强箍筋能有效改善构件的抗剪性能.Shear capability of high-strength concrete member with normal-strength steel proves to be poor, so this kind of member would suffer brittleness failure. Shear performance would be improved by using high strength stirrup ato high-strength concrete. Brittleness could be reduced as well. The research was carried out for performance of high-strength stirrup and high-strength con- crete beam by tests of 6 simple-supported beams. The study of influence on the shear behavior of beam by some factors was done as well. The ultimate strength of hoops was 800 N/mm^2 and 1 100N/mm^2 in this test. The result indicates that reasonable use of high-strength stirrup can improve shear capability of concrete beams availability.
