resumo
Recent developments in civil engineenng stmctures design and constmction allowed the creation of slender and
flexible stmctures such as towers, high-rise buildings and long span bridges. The structural properties of these
stmctures, namely the low damping capability makes them vulnerable to strong wind or earthquake actions.
In recent decades various control systems based on passive, active, semi-active and hybrid devices have been
proposed and different control strategies were developed and implemented for structural vibration control. Among
these, lhe semi-active based control hás become an important altemative to passive and active control methods as
a result of its ability to gather some of the advantages of the passive control such as the reliability of these systems
with the adaptability of the active control.
