Calibration of the load enhancement factors
Abstract This paper presents a calibration procedure capable of deriving the load enhancement factors from fully probabilistic calculations, to apply to the design of a wide range of types of structure. For this purpose the selection of a target reliability level and the load combination treatment are discussed first. Then the policy for estimating the load partial safety factors is illustrated. Under suitable assumptions, required to perform numerical computations, the calibration problem is formulated as a linear programming problem. Finally the numerical values of the enhancement factors are determined with reference to the more meaningful combinations of structural self weight, imposed dead load, wind action and snow load.
