摘要：

Human induced vibration is a common problem in the design of planking levels as both flooring or decking. The source of the vibration is the so-called "human induced loading (HIL)". Models are available for a single exciting person and for a dense aggregation of persons. Small groups of persons should also be considered in view of serviceability limit state design. This paper introduces a model for the time variant stochastic fields of forces induced by the walking of a small group of persons. A numerical example is presented dealing with the evaluation of vertical and transversal accelerations at nodes of a finite element model of an existing wood footbridge. The example considers different idealizations of the human induced excitation and the results of these models are compared to actual records. (C) 2017 Elsevier Ltd. All rights reserved.
