Fluid Viscous Damper with Overloading Protection

Design Principle

IEC’s Fluid Viscous Damper (FVD) introduces an innovative overload protection mechanism, enhancing seismic safety during extreme events. The device operates based on the principle of fluid motion through restricted passages, where damping is achieved by the resistance generated from the movement of the piston within a viscous fluid. Under normal operating conditions, the piston dissipates energy efficiently, reducing vibrations transmitted to the structure. The overload protection mechanism, a pioneering design by IEC, ensures the damper’s output force is capped at a pre-set threshold during extreme seismic forces. This prevents excessive strain on the damper and connected structural elements, preserving functionality even under extraordinary circumstances.

Suitable Applications
The FVD with Overload Protection is ideal for high-rise buildings, bridges, and historical structures located in seismically active regions. It is particularly suitable for applications requiring enhanced reliability and durability, such as: Bridges exposed to dynamic loads from both seismic and wind forces. Critical infrastructure like hospitals and airports, where safety and operational continuity are essential. Historical monuments requiring vibration control without compromising structural integrity. This innovation ensures not only seismic safety but also extended damper lifespan, reducing maintenance costs and enhancing overall project sustainability. Highlights of IEC’s Overload Protection: Enhanced Safety: Prevents excessive forces during extreme seismic events, safeguarding both the damper and the structure. Cost Efficiency: By capping forces, it reduces overdesign of structural components, minimizing material costs. Reliable Operation: Ensures performance under high-stress conditions, making it an indispensable choice for critical structures.
