| 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.

| Abstract: | 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 concrete 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/mm2 and 1 100N/mm2 in this test.The result indicates that reasonable use of high-strength stirrup can improve shear capability of concrete beams availability. |
