Abstract This study presents displacement sensitivity analysis and stiffness-based optimal design technique of shear wall outrigger system considering floor rigid diaphragm action. To verify the effectiveness and usefulness of this technique, the efficient evaluation method for four types of 50 story model with core and outrigger system is presented. To this end, isoparametric plane stress element with rotational stiffness is used for shear wall element and stiffness gradient is calculated. Also, the approximation concept can be effectively utilized to solve the large scaled problems, and member grouping technique, design variable relationships and resizing technique are considered.
