In recent years, considerable attention has been paid to research and development of structural control devices, with particular emphasis on alleviation of wind and seismic response of buildings and bridges. In both areas, serious efforts have been undertaken in the last two decades to develop the structural control concept into a workable technology. Full-scale implementation of active control systems have been accomplished in several structures, mainly in Japan; however, cost effectiveness and reliability considerations have limited their wide spread acceptance. Because of their mechanical simplicity, low power requirements, and large, controllable force capacity, semi-active systems provide an attractive alternative to active and hybrid control systems for structural vibration reduction.

PASOFAL EXPERTS helps its clients to design, assess and install structural vibration controls to prevent seismic damages of civil structures reducing undesired structural responses. Our expert team in design of Energy Dissipation Systems have been proven publishing high ranked ISI journals to show the capability of understanding the concept and implementing such devices on new and existing buildings and bridges. It is noted that, our main scope of expertise is in offering passive and hybrid control systems.  In contrast to active vibration control, passive systems are not operated by any external force or source. In the passive control approach, control devices are embedded or connected to the structural members, as shown in the figure, to improve the structural damping or increase the stiffness without any use of external force.
