以连梁剪力墙结构为研究对象，根据实际工程及规范建立足尺的精细化数值模型。分析单调水平荷载作用下单连梁、双连梁、三连梁剪力墙结构的裂缝发展状况，进而研究连梁的破坏机理。研究结果表明：连梁剪力墙结构延性性能均能满足规范要求，且双联梁剪力墙及三连梁剪力墙的延性明显优于单连梁剪力墙；在相同荷载作用下，单连梁的裂缝发展速度最快、承载力最低，而双连梁及三连梁的破坏机理基本相似。%With shear wall with coupling beams as study object and the full sized model is established in accordance with corresponding standards and en-gineering. The crack development condition of single beam, shear wall with single beam, double coupling beam and three consecutive beams is analyzed and the failure mechanisms of coupling beam is studied. The results show that all of the ductility factors meet the standardized requirements. The ductility coefficients of shear wall with double coupling-beam and three consecutive beams obviously exceed that with single-beam. Under the same load, the crack of single beam develops most rapidly with the lowest loading capacity, while the failure mechanism of both double coupling beam and three con-secutive beams shares the uniformity.
