This extensive experimental dataset corresponds to over 100 pedestrians who, one at a time, walked twice over a footbridge at 10 different pace frequency. Basic characteristics of each volunteer (weight, body height, foot length, distance from heel to metatarsal, sex and age) are reported. This dataset provides researchers and designers with useful information for improving, developing and/or validating human-structure interaction models and, in general, for studying human-structure interaction in footbridges. Data are presented in folders identified with a four-digit ID number that was anonymously assigned to each test volunteer (e.g. 0393). Each folder contains twenty files (*.mat) corresponding to each of the human-structure interaction tests carried out by the respective volunteer. The volunteer ID number is followed by a two-digit number that corresponds to the pace frequency (e.g. “0393_20” for a pace frequency of 2.0 Hz by volunteer 0393) or the letter “N” that stands for preferred pace frequency. The letters “A” and “B” at the end of the file’s name correspond to each of the two traverses per pace frequency. Each file contains two variables: “accel” and “forces”. The variable “accel” is a matrix with four columns that correspond to each of four accelerometers, and “forces” is a variable type structure composed of two matrices corresponding to the load cells at the right support (“forces.D”) and at the left support (“forces.I”). Each of these matrices are double columned, as two load cells were installed at both ends. The number of rows in each matrix depends of the duration of the corresponding test. Finally, a *.xls file that contains basic data and anthropometric measurements corresponding to each volunteer ID number is provided. The experimental campaing has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans. Informed consent was obtained for experimentation with human subjects.
