Figures 1 to 4 illustrate how various structural elements can be isolated to combat the propagation of vibrations through a building. Each concept presents its own specific constructional challenges, which must be addressed in the course of design work.
A low natural frequency of the supported structural element is critical for successful isolation. With the well-proven products of the VIB¬RAX® line, mageba can offer low-frequency building support solutions with designer-friendly dimensioning. Please refer to the product overview for further information about the individual products.
To achieve effective vibration isolation or damping, the following factors should also be considered:
Shear transmission as a result of the low horizontal stiffness of the bearing products
Avoidance of constraint forces due to temperature variations and shrinkage
Connections to stiffening building parts such as stairwells and lift shafts
The effect of enclosed areas
Possible water leakage into the damping material
Compatibility of mixed systems
mageba has in-depth experience in such matters, and is pleased to put this at your disposal.
