In the frame-shear wall structure FSWS of reinforced concrete, the coupling beam of shear wall (CB) and frame beam (FB) up the corresponding part of which has a stage of working cooperatively under horizontal load. However, the research on the whole working mechanism of the CB and FB under that stage is little. So, by taking parallel double coupling beam (PDCB) with different width (PDCBDW) which is constituted of the CB and FB as research object, the loading process of 11 PDCB are simulated under low-cycle repeated load by nonlinear finite element software. The results show that: with the increase of span-depth ratio of the FB, the yield load (YL) and ultimate load (UL) decreases, the yield displacement (YD), ultimate displacement (UD) and ductility factor (DF) increases. With the decrease of span-depth ratio of the CB, it presents rebound phenomena in skeleton curve. With the increase of the section width of the FB, the YL, UL and DF increase. With the increase of concrete strength the YL and UL increases. With the increase of the reinforced area ratio, the YL and UL increase. This implies that the span-depth ratio is an important factor which influences the skeleton curve.
