摘　　要：通过钢筋轻骨料混凝土开洞低剪力墙在低周反复荷载作用下的试验研究,探讨了洞口大小和位置对剪力墙延性及耗能性能等的影响。由于洞口角部产生应力集中,开洞墙体的开裂荷载小于未开洞墙体。洞口位置对于具有对称墙肢的小开洞剪力墙极限承载力影响不大,但对结构延性及耗能能力有一定的影响。Three light-weight aggregate concrete low-rise shear walls with opening are tested under low frequency cyclic load. The influences of the size and location of openings on the ductility and energy dissipation are studied. Cracking load of shear wall with opening is lower than that without opening due to stress concentration. The location of opening has little influence on the ultimate bearing capacity of shear wall with symmetrical wall limb, and influences the ductility and energy dissipation.
