Abstract

This paper deals with two kinds of simplified methods (Method I and Method II) to evaluate the maximum response amplitude of continuous type pedestrian bridges caused by a walking person; Method I does not require not only the eigenvalue calculation but also the dynamic response analysis, and Method II, based on the results of eigenvalue calculation, does not require dynamic response analysis. Numerical examples were evaluated out for several bridge models. It was ascertained that the evaluation value based on each method proposed in this paper was fairly in a good agreement with the computed value when a person walked on the continuous bridges with the same pace as natural frequency.
