Design Limit States
The justification stage of design can begin after the selection of possible alternative bridge types that satisfy the function and aesthetic requirements of the bridge location has been completed. An important goal of design is to prevent a limit state from being reached. The determination of an acceptable margin of safety (how much greater the resistance should be compared to the effect of loads) is not based on the opinion of one individual but on the collective experience and judgment of a qualified group of engineers and officials. In the U.S. highway bridge design community, the American Association of State Highway and Transportation Officials (AASHTO) is such a group. To understand where we are today, it is helpful to look at the design procedures of earlier AASHTO specifications and how they have evolved as technology changed.
