自2010年以来，AIJ标准中的剪力墙设计采用了与开口高度相关的新折减系数。该因子虽然在理论上提出，但尚未得到实验验证。此外，根据MLIT（日本政府）法规，其他折减系数在法律上规定了剪力墙设计。本文报告了实验室测试，以验证这些减少因素和实验结果之间的协议。对3个1/6缩尺剪力墙试件进行了不同开洞形式的试验研究。因此，得出的结论是，AIJ折减系数低估了由于开口而导致的强度下降，但MLIT折减系数高估了。
A new reduction factor related to opening height has been adopted for shear wall design in the AIJ standard since 2010. This factor has not been verified experimentally, while it was presented theoretically. Moreover, the other reduction factor legally regulates shear wall design according to the MLIT (Japanese government) regulation. This paper reports laboratory tests to verify agreements between these reduction factors and experimental results. Three 1/6 scale shear wall specimens were tested with different opening configurations. Consequently, it was concluded that the AIJ reduction factor underestimated the strength drops due to openings but the MLIT reduction factor overestimated.
