Thank you all for your replies and help! After a bit of hair pulling, my problem has been solved. Luckily AASHTO recently added this offering in their bookstore: "AASHTO LRFD Bridge Design Specifications, 3rd Edition with Interims, PE Exam Edition." [thumbsup2] They note that it is...

Thank you for your responses. The Structural I exam contains approximately 20% bridge knowledge questions, no opting out: http://www.ncees.org/exams/professional/pe_structural_1_exam_specs.pdf So I guess I'm stuck with getting the new book and hoping that I get close enough with it...

What are the differences between the following standards: #1 - "AASHTO LRFD Bridge Design Specifications, 3rd edition, 2004, with 2005 & 2006 Interim Revisions" & #2- "AASHTO LRFD Bridge Design Specifications, Customary U.S. Units, 4th Edition, 2007 (or the same in SI Units)" I haven't...

For anyone who was interested in this thread, if you use the tabulated values for your wood shear panel walls, I haven't found any way to get out of the provision of using a 3x when in SDC D/E/F for applied seismic &/or adjusted wind loads over 350 plf. However, in the 2006 IBC, the 2-2x in...

Thanks, structural aggie. Yes, with footnote e. for this IBC table, 3x's at panel joints are always required for edge nailing spacings of 2" o.c. (and footnote f. requires 3x's at panel joints for some shear wall constructions with edge nailings at 3" o.c.). So, it does make sense that close...

Yes, GNight, the IBC does base it on the capacity of the wall; but does the UBC make any distinction between wind and seismic? Often the provisions for seismic are more stringent than for wind. It's not clear to me in this case. In my office, we have a table with typical shear walls we use...

In the IBC 2003, Table 2306.4.1 (p.469), footnote i. states that "In Seismic Design Category D, E, or F, where shear design values exceed...[350 plf] (ASD) all framing members receiving edge nailing from abutting panels shall not be less than a single 3-inch nominal member. ..." My question is...
