Building vibration due to road traffic
RE investigated real-time floor acceleration in a 5-story building which was displaying vibration and shaking due to road traffic.
Floor/Building Vibration
Large machines operations cause vibration to its supporting floor as well as its sheltering structures. Vibration is measured and evaluation is made accordingly
Building vibration caused by machines operation
Large machine operations can cause vibration to the supporting platforms as well as the sheltering structures. Vibration is measured, and evaluation is made accordingly. In an example case of this, undertaken by RE, when the machines in the premises started operating, strong vibration was observed in the sheltering structure, and large deformation was visualized in long-slender steel columns. The reason was found to be an accidentally matching between machine vibration frequency and 1st natural frequency of the columns. Resonance therefore occurred.
Measurement of floor vibration caused by machines operation
In one case undertaken by RE, it was found that machine vibrations during the operations caused strong vibrations to the floor underneath. Thus, accelerometers were used to capture real-time floor and machine vibrations for all axes.
