This study aims at improving a strength reduction factor r3 related to opening height for RC shear walls in the ALT design standard. FEM analyses for RC shear wall specimens with vertically aligned openings were conducted to evaluate contributions of the wall components to the overall lateral strengths. As a result, the flexural resistances of the partial walls divided by the openings were overestimated by r3, while the shear resistances of the beams between the openings agreed with those by r3. Therefore, a new slrenglh reduction factor newr3 was proposed on the basis of a flexural slrength reduction index α for this type of wall. Consequently, the estimations for the ultimate strengths of the above specimens using newr3 showed good agreements wiHi the experimental strength reductions.
