摘要

•MSJC and Canadian codes provide unsafe shear strength predictions for PG-RM walls.•A modified MSJC equation is proposed to improve shear strength predictions.•A normalized shear demand parameter is a better damage indicator than story-drift ratio.•Bond-beam PG-RM walls present lower deformation capacity than bed-joint PG-RM walls.
