Abstract
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.
