AB - In the field of civil engineering, live loads are related to the use of the floors of buildings and dwellings. Live loads are produced by weight of people and furniture. Such loads generate internal physical effects such bending moments, shear forces or axial forces on structural elements that can show high uncertainty in magnitude and position. This work proposes the application of a physical-mathematical model which considers such uncertainty when forecasting maximum probable live loads to be used in structural analysis and design of elements. To do so, field data of live loads acting on different floors of 20 dwellings built in San Jose de Cucuta, Colombia, were collected and used to verify the model validity. As a result, it was observed a small difference in forecasted live loads with respect to the live loads prescribed by the national and international structural design standards. Live loads forecasted using the model describe modern trends of use of floors and can be used as safe values for designing structural elements. Physical quantities related to bending moment effects resulted to influence importantly the obtained maximum loads values.
