    摘要
  • 摘要: 为研究型钢轻骨料混凝土梁的剪切性能,进行了15根型钢轻骨料混凝土梁和2根型钢普通混凝土梁的抗剪性能试验。试验表明,在型钢混凝土梁中配置一定的箍筋可避免剪切粘结破坏的发生;本次试验的17根试验梁中有7根发生斜压破坏,10根发生剪压破坏。与文献[1]的试验共同表明,剪跨比对试验梁的破坏形态具有决定性的影响;当剪跨比1.5时发生斜压破坏;剪跨比1.53.0时发生剪压破坏;剪跨比3.0时发生弯曲破坏;同时型钢的存在使得受剪破坏时的脆性性能得到较大改善。
    Abstract: In order to study the shear performance of steel reinforced lightweight aggregate concrete beams, fifteen steel reinforced lightweight aggregate concrete beams and two steel reinforced normal density concrete beams were tested. The results of test have indicated that the occurrence of shear adhesive failure could be avoided if reinforced certain stirrups in section steel concrete beams. Among seventeen testing beams, 7 were slanting pressure failure, and the other 10 were shear pressure failure. This test, as well as the test of Ref. [1], has showed that the ratio of shear to span had decisive influence on the failure mode of testing beams. When the ratio of shear to span satisfied 1.5, slanting pressure failure happened; when 1.53.0, shear pressure failure happened; and when 3.0, flexural failure happened. At the same time, the existence of section steel made the brittle performance of shear failure improve remarkably.
