The development of construction has led to recent structures that are designed in slender figures, giving them high flexibility that are more affected by wind-induced vibration. If a structure is exposed to wind-induced vibration for a long period of time, it may not only negatively affect occupant comfort but may also cause structural instability.
Moreover, vibration may be induced through various traffic loads. In many cities habitability of building is often hindered with vibration induced from train and automobile traffic. Vibration in high rise buildings, where many of them are used for residential or commercial purposes with residents living or working inside, is a nuisance that can greatly hinder the habitability. The International Organization for Standardization (ISO) and other organizations that provide structural guideline such as AIJ(Architectural Institute of Japan), and NBCC(National Building Code of Canada) have classified the magnitude of the vibration numerically with consideration on the type of vibration and the human perception to the vibration to recommend specific criterion for vibration level on the structure to satisfy. |
