Experimental investigation on vibration sensitivity of an indoor glass footbridge to walking conditions
TL;DR: The dynamic performance of an existing indoor suspension glass footbridge is taken into account and explored via Operational Modal Analysis (OMA) techniques, and variations in the imposed human-induced vibrations, such as the movement features, number of occupants, ambient conditions, size effects and mechanical restraints are discussed.

Uncoupled Wi-Fi Body CoM Acceleration for the Analysis of Lightweight Glass Slabs under Random Walks
Chiara Bedon,Salvatore Noe +1 more
TL;DR: In this article , an uncoupled experimental investigation is proposed to numerically address the accuracy and potential of low-cost laboratory body measures for vibration analysis of laminated glass slabs to support (or even replace) field tests or more complex calculation approaches.
Effects of Vertical Ground Motion on Pedestrian-Induced Vibrations of Footbridges: Numerical Analysis and Machine Learning-Based Prediction
Xinxin Wei,Bo Fu,Wen Jing Wu,Xin-rui Liu +3 more
TL;DR: In this paper , the authors investigated the effects of vertical ground motion on pedestrian-induced vibrations of footbridges and proposed an amplification factor to quantify the amplification effects of ground motion.
Experimental and analytical study of vibration parameters in waffle concrete slabs
TL;DR: In this article, in situ experimental tests were carried out on twenty-six floor slabs using the heel drop as impact source, accelerometer and mobile phone to register the natural frequencies and subsequently modal damping ratios.
