Abstract:
A statistical treatment of the problem of combination of different types of loadings involves a suitable definition of each of the loads to be combined. In the idealization adopted each load is assumed constant during given intervals of time, and variable from interval to interval according to an uncorrelated stochastic process. Further, variability from structure to structure and variability in time are assumed to be equivalent. . .The results obtained give a clear understanding on how to perform the combination of loads and on how to choose the load factors. . .
