Time for everyone to wake up. The 2% error rate does not seem that high, but what was missed in that analysis, is that if just one formula is completely off, your entire design can be 100% off. That is what you have to keep in mind. What one has to consider is that this is a legal document. When we as engineers follow this 'technical publication', we become 'legally' responsible for mistakes that are out of our control. Now can someone tell me for sure that all the errors have been picked up? Will a new errata be published 3 months from now, 2 months after I completed a new project? Am I safe in basing my calculations on a publication that is so full of error? Keep in mind that the same problems were encountered with the '97 UBC and the 3 volumes of the Seismic manuals, and it took a couple of years to iron thing out. That's why there is no excuse for the sloppy proofing this time around! There has to be more proof reading, and if more time is needed, than so be it. Where is the rush? Are buildings collapsing all around us? Or is this a money making venture? More mistakes will be made by practicing engineers by this constant code changes, than if the existing code is just left in place for a while longer. I don't want to get personal with anyone, I just have to vent.

Most constr. docs errors are typos inwhich we can interpret the meaning, (ie. "wood beam" spelled "wood bem." But a mistake in a formula in a technical publication can have disasterous results, (i.e. a "greater than" sign reversed to "less than"). From the postings, it sounds like ASCE dropped the ball at our expense. Larry Hauer S.E. >From: "Mark E.
