Abstract: A great number of floor live load data are gathered based on the investigation of Auchan supermarkets. Since live loads on floor are usually expressed in terms uniformly distributed loads for design purpose, the sustained live load and the transient live load on floor calculated respectively with the average load in unit area and in batten area. Making use of mathematical statistics analysis, probability distributions and statistical parameters of sustained and transient quality of supermarket floor live load is studied. Thereby the distributed models and parameters of the sustained live load and the transient live load on supermarket floor obtained at design reference period T= 50 years. Our country's characteristic value of live load on supermarket floor is advanced
