This research advances creation of a new generation of adaptive/smart structures with self‐modification capability by designing a predetermined number of members as actively controlled members. The computational model and high‐performance parallel algorithms for optimal control of large structures recently developed by the authors are applied to multistory buildings. Four different schemes for placement of controllers are investigated. Three types of dynamic loadings are considered: earthquake ground motion, periodic impulsive horizontal wind loading on the exterior joints of the structure, and asymmetric periodic impulsive wind loading on the exterior of the structure modeling a twister. Results are presented for three multistory building structures with curved beams and setback representing both space moment‐resisting and braced frames. It is demonstrated that through a proper selection of the weighting factor, the response of a multistory building structure can be reduced substantially to a fraction of the response of the uncontrolled structure at a practically feasible maximum required actuator force. Recommendations are made on the placement of the controllers for various types of structural configurations.
