The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in nine parking garages in Chicago and Champaign-Urbana, Illinois, and Cambridge and Boston, Massachusetts. Based on the survey data, statistical analyses were carried out of the Equivalent Uniform Distributed Loads (EUDL), which produce the maximum column axial loads and beam midspan moments that the building is expected to experience during its lifetime. The dynamic amplifications due to vehicle motions on the decks and ramps were also investigated. The results suggest a possible reduction of the design live load from the current value of 50 psf, as stipulated in the ASCE-7 and Uniform Building Code, to 40 psf but with no allowance for reduction according to bay area.
