Integrated design of inelastic controlled structural systems

This paper addresses the integrated design of civil engineering inelastic structures with embedded control systems and devices. Simultaneous optimization of such controlled structures is considered, showing that new structural forms and configurations can be achieved through integrated design. An optimization procedure for controlled structural systems is developed. The optimal design of (i) an SDOF steel portal frame and (ii) an 8-DOF shear-type structure is used as examples to illustrate the feasibility of the proposed approach, which reduces the structural weight of the buildings by incorporating active control elements while preserving the same performance objectives. The numerical results illustrated by these two examples show practical applicability, especially for the case of high-rise buildings.
