Abstract

Prediction of structural vibrations due to vertical loads generated by pedestrians is an assignment that many engineers involved with footbridge design have encountered. Often, the problem matter is not ultimate limit-state-requirements, but concern is on serviceability-limit-state requirements in the form of potential excessive structural vibrations. The nature of human locomotion dictates that the action of pedestrians on footbridges is random. This also has the effect that the footbridge vibrational response is random and potentially depends on a set of walking parameters (pacing speed, load amplifications factors, pedestrian weight, etc.) and the stochastic nature of these parameters. The paper will address issues of predicting footbridge vibrations in this context, taking offset in artificial footbridges. Monte Carlo simulations and Newmark time integration will be employed for determining footbridge vibrations.
