Structural Control in Strong Wind and Moderate Seismic Region
In the past three decades, most of the research efforts in structural control were focused on the
enhancement of either the safety of buildings and structures in regions of high seismicity or the
serviceability performance of buildings and structures in regions of strong winds. Less attention was
paid to the integrated design of structural control systems to satisfy both the safety requirement for
moderate seismic events and the serviceability requirement for strong winds. Such a task may be
difficult to be accomplished using the passive control technology; however, the semi-active control
technology with proper control devices and algorithms can be developed to fulfill this challenge.

Durability and Reliability of Smart and Control Systems
Reliability of active and semi-active control systems is a principal concern of building owners. Research
in predicting the performance of smart control systems and their reliability is needed before these
technologies will see any significant use in USA. The panel points out that in most cases, semi-active
controllers are used based on their passive control capabilities Gust in case the semi-active control fails
to work).

EDUCATION
A critical issue for the future of smart structures is to create cross-cutting educational programs to
prepare the next generation of engineers to take advantage of this technology in tackling the challenges
of today's rapidly evolving society. Educational programs should be developed that integrate academic
