［摘要］為研究型鋼再生混凝土梁的受剪性能，進行了10根型鋼再生混凝土梁和2根型鋼普通混凝土梁的抗剪性能試驗，考慮了再生粗骨料取代率、剪跨比和混凝土強度3個影響因素。12根試驗梁中有8根發(fā)生剪切斜壓破壞，4根發(fā)生彎剪破壞。試驗表明，在型鋼再生混凝土梁中配置一定數(shù)量的箍筋可避免剪切粘結(jié)破壞的發(fā)生，型鋼再生混凝土梁與型鋼普通混凝土梁受力過程相似，且強度并沒有明顯降低。

Abstract:In order to study the shear performance of steel reinforced recycled aggregate concrete beams, ten steel reinforced recycled aggregate concrete beams and two steel reinforced normal aggregate concrete beams were tested. The replacement ratio of recycled coarse aggregate, the shear span ratio and the concrete strength were considered. Among twelve testing beams, 8 beams failed for shearing diagonal compression, and the other 4 beams failed for bending and shearing. The test results show that the occurrence of shear adhesive failure can be avoided if a certain number of stirrups are set in steel reinforced recycled aggregate concrete beams. In addition, steel recycled aggregate concrete beams have the similar stress process with the steel reinforced normal aggregate concrete beams, and the strength is not reduced significantly.

Keywords:steel reinforced recycled aggregate concrete; beam; shear performance; experimental study
