摘　　要：设计了两个足尺的单层双肢剪力墙试件,其中一个带有传统的钢筋混凝土连梁,另一个连梁中安装有改进的三角钢板阻尼器,通过拟静力试验研究两个试件的屈服破坏模式和抗震性能。研究结果表明:这种新型连梁的耗能能力和变形能力明显优于传统连梁,刚度和强度退化小于传统连梁;新型连梁的变形和耗能都集中在阻尼器中,混凝土连梁基本保持完好,阻尼器能够很好地控制结构的损伤,有利于实现连梁震后的可更换。Two full-scale single-story coupled shear wall specimens were designed,one with traditional reinforced concrete coupling beams and the other with improved triangular steel plate dampers.The yield failure modes and seismic performance of the two specimens were studied by quasi-static tests.The results show that the energy dissipation and deformation capacity of the new type of coupling beams were obviously larger than those of the traditional coupling beams.The stiffness and strength degradations were less than those of the traditional coupling beams.The deformation and energy dissipation of the new type of coupling beams were concentrated in the dampers.The concrete coupling beams were generally in good condition.The dampers can control structural damage well,which is conducive to the replacement of the coupling beams after earthquakes.
