Abstract:

Use of load factors in ultimate design is compared to elastic theory and allowable stress method; variables affecting load factor of bridge sections analyzed, indicating wide divergence when designed on basis of no tension in concrete; significance of load distribution, load repetition, and meaning of yield point and usable strengths.
