Office floor vibrations: modal parameter identification and vibration monitoring
Several people working on the 2nd floor of an office building complained about disturbing floor vibrations. The building consists of five floors. In the contrary to the other floors, the 2nd floor slab has no floor-to-ceiling secondary walls neither beneath nor on top of the slab. The modal parameters of four floors were identified using ambient vibration testing (AVT)-technology and a 5-kg-med...
متن کاملImpedance Modeling for Prediction of Train Induced Floor Vibrations
Laboratory and manufacturing facilities are frequently located in areas that experience high-frequency (greater than 30 Hz) environmental vibration. Such vibrations are a concern for the proper functioning of sensitive laboratory devices, precision manufacturing equipment as well as human comfort. A simple method to accurately predict the magnitude of high-frequency floor vibrations would allow...
متن کاملPelvic floor stimulation: what are the good vibrations?
OBJECTIVE The aim of this study was to determine if two different whole body vibration, sinusoidal vibration (SV) and stochastic resonance vibration (SRV), using various intensities lead to a reactive activation of pelvic floor muscles. STUDY DESIGN We compared the pelvic floor muscle response of a healthy control group with that of a post partum group with weakened pelvic floor contraction. ...
متن کاملMitigation of Train-Induced Floor Vibrations in Multi-Story Buildings Using a Blocking Floor
A new method is developed for reducing train–induced floor vibrations in buildings. Vibration transmitted through building columns to the upper floors can be mitigated by considerably increasing the thickness of a lower floor, which is named the “blocking floor”. This can be a desirable and inexpensive solution for vibration mitigation. The work presented by this paper shows the ability of an i...
متن کاملLow-cost step aerobics system with virtual aerobics trainer
In this paper a low-cost step-aerobics instructor simulation system is presented. The proposed system analyses a given song to identify its rhythmic pattern. Subsequently, this rhythmic pattern is used in order to issue a set of steps-aerobics commands to the user, thus simulating a training session. The system uses a Wii Balance Board to track exercises performed by users and runs on an Androi...
