　　通过3根钢纤维混凝土剪力墙连梁在低周反复荷载作用下的试验，研究了钢纤维体积率等对连梁破坏形态、滞回曲线、变形及耗能性能的影响，在不同钢纤维体积率的连梁试件中，试件的破坏形态不相同，构件的承载力和位移延性大小不同。结果表明，在钢筋混凝土连梁中加入足够的钢纤维，能够有效地改善连梁的变形与耗能能力。

Through the experimental study on the three coupling beams of steel fiber concrete shearing walls under the cyclic reverse load, the influences of the volume ratio of steel fiber on the destruction modes, hysteresis curves, defor-mation and energy costing of the coupling beams are described. During the different volume ratio of steel fiber of the cou-pling beams, the destruction modes are different, and the capacity and displacement ductility of the specimens are also different. The results show that enough volume ratio of steel fiber in the coupling beams can obviously improve the defor-mation and energy costing of the coupling beams.
