Web12 feb. 2008 · I've converted to LRFD (after using ASD more than 15 years) and it's not that big of a deal to use nor that cumbersome once you start using it. Both methods have been set up to give similar results and both methods are "good engineering practice." But I can't agree with the implication that ASD is somehow superior or offers more control to LRFD.
