摘要：为研究双肢剪力墙结构大剪跨比（μ≥2.5）钢筋混凝土耗能连梁的力学性能。设计了3个剪跨比为3.0的钢筋混凝土连梁构件，其中2个为普通混凝土连梁，1个为设置消能装置的连梁，通过低周往复加载试验，对比分析了裂缝发展、连梁转角、荷载-位移曲线、骨架曲线、构件刚度以及耗能能力。分析结果表明，采用金属耗能装置的钢筋混凝土连梁可以有效降低连梁自身混凝土段和墙肢的损伤，主要变形集中在金属耗能装置中，可以很好地实现震后构件的快速更换，带阻尼器连梁没有出现普通连梁承载力超强的问题。 Abstract: In order to study the mechanical properties of double shear wall structure with large shear-span ratio, three reinforced concrete beam connectors with a shear to span ratio of 3.0 were designed, and two of them were ordinary concrete beams and one was a beam with an energy dissipation device. Through low-cycle reciprocating loading test, the crack development, beam Angle, load-displacement curve, skeleton curve, component stiffness and energy dissipation capacity were compared and analyzed. The analysis results show that the reinforced concrete beam with metal energy dissipation device can effectively reduce the damage of the concrete section and the wall limb of the beam itself, and the main deformation is concentrated in the metal energy dissipation device, which can well realize the rapid replacement of the components after the earthquake, and there is no problem of super bearing capacity of ordinary connecting beams with dampers.
