Dataset of single-pedestrian vertical human-structure interaction measurements in a footbridge

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.

本大规模实验数据集涵盖100余名行人，每名行人依次以10种不同步频分别在人行桥上行进两次。本数据集记录了每名志愿者的基础生理特征，包括体重、身高、足长、足跟至跖骨的距离、性别与年龄。本数据集可为研究人员与设计师提供宝贵信息，用于优化、开发及/或验证人-结构相互作用（human-structure interaction）模型，总体而言可用于人行桥场景下的人-结构相互作用研究。数据以匿名分配给每名测试志愿者的四位数字ID作为文件夹标识（例如0393）进行存储。每个文件夹包含20个*.mat格式文件，分别对应该志愿者开展的所有20次人-结构相互作用测试。志愿者ID后接两位数字，代表对应的步频（例如"0393_20"代表志愿者0393以2.0Hz步频行进），或字母"N"，代表自然优选步频。文件名末尾的字母"A"与"B"，分别对应同一步频下的两次行进测试。每个文件包含两个变量："accel"与"forces"。变量"accel"为四列矩阵，分别对应四个加速度传感器的采集数据；变量"forces"为结构体类型变量，包含两个矩阵，分别对应右侧支座（"forces.D"）与左侧支座（"forces.I"）的测力传感器数据。每个矩阵均为双列数据，因为支座两端均安装了两个测力传感器。每个矩阵的行数取决于对应测试的时长。此外，本数据集还提供一个*.xls格式文件，记录了每位志愿者ID对应的基础信息与人体测量学数据。本实验研究严格遵循世界医学协会（World Medical Association）制定的《赫尔辛基宣言》（Declaration of Helsinki）中涉及人类受试者的实验伦理准则开展。所有人类受试者均已签署知情同意书。
