Abstract

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.
