Human-induced Vibrations: Methods, procedures and examples for the assessment of structural serviceability

Human-induced vibrations are not a new phenomenon for building structures, but due to increasing architectonical and serviceability requirements (e.g. with respect to slenderness) their influence and importance are growing. In particular, for the construction of concert halls, stadiums, gymnasiums and sports halls, pedestrian bridges and other slender and light structures the assessment and evaluation of the vibrational behavior is an essential part of the overall design. Human-induced vibrations (e.g. by walking, swaying, hopping and jumping) in these buildings can affect the serviceability, and even the structural safety. The intension of this paper is to point out the theoretical basis and the methods and procedures for the evaluation of structural serviceability and safety for human induced vibrations, especially for stand structures and the corresponding dominant load case "jumping". Also the application of these methods and procedures is demonstrated on a practical example. For the estimation of expected vibrations and human-induced loads, a simplified procedure, which originates from earthquake engineering, has been developed. This procedure and its application are presented and discussed.
