Abstract:
This paper presents an important aspect of the structural design of concrete bridges under various combinations of loading. 'Load Factors', which are quantities used to define the pattern and magnitude of design loadings, are evaluated from a statisitcal point of view in such a manner as to assure a desired level of safety for the structure.
