Case Studies of Structures with Man‐Induced Vibrations

Periodic human body motions can lead to excessive structural vibrations. In normal cases, frequency tuning a structure is a useful countermeasure. In special cases, lower structural frequencies than those resulting from the presented frequency‐tuning criteria may be accepted. This is confirmed by experiences with practical cases: Ten case studies of footbridges, gymnasiums and sports halls, dance halls and concert halls without fixed seating, concert halls with fixed seating, and high‐diving platforms are presented. In some cases, existing buildings had to be upgraded. In other cases, where structures were still in the planning stage, significant modifications to the design were necessary.
