摘　　要：改善高强混凝土梁的抗剪性能对提高结构安全性具有重要意义。总结了近十几年来国内外对高强混凝土梁、型钢高强混凝土梁及预应力高强混凝土梁抗剪性能的研究现状及存在且亟需解决的主要问题。结合预应力钢筋、型钢和超高强混凝土的优点,对预应力型钢超高强混凝土梁的可行性及优越性进行了展望。Improving the shearing performance of high-strength concrete beam has significance for increasing the structural security.Summa- rizes status quo of study on shear behavior of high-strength reinforced concrete beam, steel reinforced high-strength concrete beam and prestressed high strength reinforced concrete beam over the last decade.The existing problems were also presented.Baced on the advantages of pre-strcsscd, section steel and super high-strength concrete, the practicability and the superiority of the prestressed and steel reinforced super high strength con- crete beam is prospected.
