Integrated Design of Smart Structures [PDF]

open access: yesAdvances in Science and Technology, 2008
Much of structural control research and applications in civil engineering have been concerned with structures equipped with passive, hybrid, or active control devices in order to enhance structural performance under extraordinary loads. In most cases, the structure and the control system are individually designed and optimized.
