AIJ规范中钢筋混凝土剪力墙设计采用了与开洞有关的强度折减系数，而偏心开洞和对角开洞的多层剪力墙没有经过试验验证。通过3个1/4缩尺剪力墙试件的室内试验，验证了不同开洞布置的多层剪力墙的结构性能。在此基础上，提出了一种将集中荷载简化为分布荷载的加载方法，并应用于试验。结果表明，由于开孔的非对称布置，开孔试件在正荷载和负荷载作用下的最大承载力和破坏形态表现出不同的趋势。
A strength reduction factor related to door openings has been adopted for RC shear wall design in AIJ standard, while multi-story shear walls with eccentricallyaligned door openings and diagonally-aligned door openings have not been verified experimentally. This paper reports laboratory tests of three 1/4 scale shear wall specimens, verifying the structural performance of multi-story shear walls with different layout of door openings. Furthermore, based on the analytical results, a new loading method with a couple of concentrated loads simplified distributed loads was proposed and applied to the experiment. Consequently, the seismic performance of the specimens with openings showed different tendency on the maximum strength and failure pattern under the positive and negative loads due to the unsymmetrical layout of the openings.
