摘　　要：为了探究改善钢筋混凝土短肢剪力墙抗震性能的方法,制作了2个设置型钢混凝土端柱的短肢剪力墙试件,并对其进行低周反复循环加载试验。通过试验研究,比较2个试件的开裂荷载、屈服荷载和极限荷载的数值,设置核心型钢管混凝土端柱的短肢剪力墙的数值要高于拼合形型钢混凝土端柱的短肢剪力墙,其强度衰减也相对较为缓慢;2个试件的破坏形态都为弯剪型破坏,其承载能力较高,它们的延性、耗能大大优于一般钢筋混凝土短肢剪力墙结构,对于改善钢筋混凝土短肢剪力墙的抗震性能起到了很好的效果。To explore methods for improving the seismic resistance of reinforced concrete short-limb shear walls,two specimens of short-limb shear walls with steel-reinforced concrete columns were produced and subjected to low-cycle repeated cyclic loading tests.Through experimental studies,the numerical values of cracking load,yield load,and ultimate load of the two specimens were compared.It was found that the values for the short-limb shear wall with a concrete-filled rectangular steel tubular column were higher than those for the spliced steel-reinforced concrete column,and the strength decay of the former was relatively slower.The failure modes of both specimens were flexural-shear failure with higher load-bearing capacities,and their ductility and energy dissipation were significantly better than those of conventional reinforced concrete short-limb shear walls.This innovation has demonstrated effective improvement in the seismic performance of reinforced concrete short-limb shear walls.
