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, however, cost effectiveness and reliability considerations have limited their wide spread acceptance. Figure below shows the passive system mechanism when install in a structure.

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.

In this direction, we have introduced new and innovative solutions to the markets, which, in time, have formed the common way of constructing. A good example of such a solution is the Bar Damper (BD), which is a passive structural control system made of plates and bars. The BD is mainly proposed to protect existing and new civil structures under different levels of ground motions. For further information please visit our PUBLICATIONS page.
