Structural DynamicsWe can also preformed vibration analysis on components of a buildings or other assemblies to design for time varying or impact loads.
We often consult with building owners about vibrations of floor systems. One notable project was to help a client reduce floor vibrations due to adjacent construction. The on-going construction was causing building vibrations that degraded preformance of several pieces of medical equipment. Through vibration monitoring and dynamical analysis, we were able to add a few structural members to reduce the vibrations to acceptable levels for the very senstive medical equipment.
Video below shows the 4 modes of vibration for a floor system.
