A critical aspect in the design of civil engineering
structures is the reduction of response quantities such as
velocities, deflections and forces induced by environmental
dynamic loadings (i.e., wind and earthquake). Structural
control methods are the most recent strategies for this
purpose, which can be classified as active, semi-active,
passive, and hybrid control methods [1]. Control methods
have been slow in their acceptance in the structural design
community because the systems are often prohibitively
complicated, large and expensive. Over time, however, their
utility is becoming more recognized and improvements in the
technology are making them more viable options in new
construction and retrofits.
