Coincidentally, this is about the time that personal computers were becoming more commonplace, which is a good thing because the number of computations needed to complete an LRFD design increased exponentially from those required using ASD and traditional load factor design.

Also, a simple analysis shows that the tandem axle does not control over the standard truck for spans less than about 14 feet. Remember me for one month. By Ron Thornton, P. Search book title Enter keywords for book title search.
Does the LRFD Standard Work for all Precast?
Are you sure you want to empty the cart? The ultimate load is then compared to the nominal strength of the element. While there may have been some differences in load factors and serviceability criteria between the AASHTO Standard Specification and the American Concrete Institute, the method of design and computations for many years were similar.
Need more than one copy? Once the ashm determination is made, the engineer has to go back and compute service load stresses, just like the ASD method, in order to check serviceability criteria for crack control.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These standards define specific loading requirements for traffic conditions that are consistent with AASHTO standard specification and they reference ACI for design methodology.
