Tuned mass dampers (TMDs) are used to reduce vibration in a variety of structures: floors, long-span structures, bridges and tall towers. Each requires a different approach. We provide analysis and design for all types of TMDs and have extensive experience in the design of traditional solid and liquid dampers.
We are also at the forefront of the development of a new damping method, the fluid harmonic damper (FHD), which uses a NASA-developed fluid-structure calibrating device to precisely tune the behavior of water in a pipe. FHDs control vibration using only a third of the mass needed in traditional dampers, so they take up less space and can be supported on lighter structures – characteristics that make them feasible for installation in existing as well as new structures.
