Present building codes regard live loads caused by human movement as deterministic; values are based upon experience and tests run in 1912, 1922, and 1932. An experimental project to statistically characterize these dynamic loads is described. Loads resulting from seven different motions, performed by individuals and groups, were recorded using a data acquisition system consisting of a force platform, signal conditioning, and analog-to-digital conversion equipment; an IBM-PC serves as the system controller. Interactive computer programs were written for the IBM-PC to determine the descriptive parameters for all loading types. An approach is described for selecting and calculating loads imposed by individuals and groups using analytical models.
