Sound and Structural Vibration | ScienceDirectPowerful computational methods and procedures for the numerical analysis of structural vibration, acoustical fields and acoustical interactions between fluids and structures have been developed and these are now universally employed by researchers, consultants and industrial organisations.
Beams Natural Vibration Frequency - Engineering ToolBoxVibrations in a long floor span and a lightweight construction may be an issue if the strength and stability of the structure and human sensitivity is compromised. Vibrations in structures are activated by dynamic periodic forces - like wind, people, traffic and rotating machinery.
Vibration - Introduction : OSH AnswersThe study of health effects of vibration require measures of the overall "pressure waves" (vibration energy) generated by the vibrating equipment or structure. Vibration enters the body from the part of the body or organ in contact with vibrating equipment.

System Identification of Tall Vibrating Structuresvibration records of tall structures is reported. Ambient vibration responses under natural wind conditions of five tall structures in Tokyo and Yokohama were recorded. The ambient data thus obtained were analyzed by four system identification methods: filtered correlation, spectral moments, spectral density, and two-stage least square.
