  1. I would say R = 3.0, steel system not detailed for seismic resistance since you have cable bracing. However, you do say something about "blending the lateral resistance" which might require the R=1.5 value. In some buildings I do, we have interior steel braced frames, and intermediate precast wall panels at the perimeter. We use R=3 since the interior steel frames have the lower value. The foundation system used doesn't dictate your R value from everything I have come across.
  2. I would use ASCE 7-10 - Chapter 15 - Seismic Design Requirements for Non-Building Structures, Table 15.4-2 since a deck is not a building or similar to one. There isn't anything in that table matches wood decks except "All other self-supporting structures, tanks, or vessels not covered above or by reference standards that are similar to buildings." That is listed as R=1.25. Might be conservative, but probably won't break the bank if you are already using R=1.5.
  3. I guess I should modify that by saying that I hope to have the books ready as soon as they announce the code standards for the October exam, which would be in April-May time frame.
  4. I don't. All I know is that April will be AASHTO 7th edition. Hopefully you don't get caught on an AASHTO code change. There are significant differences between the AASHTO 7th and 8th editions. A lot of it is just organizational, but some of it is fairly major. For instance, wind loads are similar to calculating wind loads on buildings in the 8th edition. On the surface, this is probably a simplification, but (as you will see) is quite different than how it is done in earlier editions. I'm working on updating my book now in anticipation of the eventual change to AASHTO 8th edition and it is quite the effort, unfortunately.
  5. Can't forget about those "footers" either.
  6. 1st thing I would do is to tab your AASHTO code book. In the Tips and Recommendations portion of my book I actually have a page of tips regarding tabs. The tabbing will start the process of learning the layout of the code. Just kinda make general mental notes of how the code is laid out, etc. This should take a few hours given the volume of AASHTO code. Once you have done that you should have a general idea of where to find stuff. Loads in chapter 3, concrete in chapter 5, etc. I would do the problems without looking at the solutions first. But if it is taking you say 15 minutes and you can't even find it in the code, then go to the solution. I would try to study as much like the exam experience as I could. Use the index, etc. Also, doing the problems without the solutions will reveal incorrect ways of thinking that you may have. Also, one thing I should mention, some of the problems could be "Six Minute Solution" problems but if it takes you longer than 6 minutes don't get discouraged. In some cases I added an extra step that would make it a "longer than 6 minute" problem so additional concepts could be introduced. Best of luck on the exam!
  7. I just flipped through really quick. May be handy if you have to draw a detail on the essay questions. Or if you have a question asking what is the correct detail, etc. Might help in your studies in applying the code correctly too, but then you may find that you don't need it during the exam.
  8. Yeah, I agree, I didn't have the "official" IBC code book. I just printed out chapters 16 through 23 (ie just the structural chapters).
  9. I can answer 2 & 3. 2) Split the exam. Too much to study for all at once. After the taking the vertical exam Friday, you are too fried to gear up for the lateral exam Saturday. When I took it, I did lateral first since I thought it would be the more difficult portion, but what I found is that it was easier to study for and the vertical exam was quite difficult. 3) Might as well start now if you are pretty sure you are going to be taking it in October. But start in April at the latest to give yourself 6 months. This is recommended for only taking 1 component.
  10. Yes, AISC 341 is in the back of the Seismic Design Manual, along with AISC 358 - Prequalified Moment Connections. The NCEES specs refers to the manuals for both Steel Design and Seismic. Plus the manuals have tables that will help you solve problems faster. For the current SE exam you need the 2010 (red) editions of the steel manuals.
  11. You are probably OK with the 3rd edition of the PPI practice exam. You are more going for practice with taking the exam and the pace you will need to maintain. As opposed to knowing if a certain concept in the code was moved to a different section. You need to be aware of that, but that's not what I concentrating on when I took the practice exams. Take the exams just like the real test though. Start at 8am-noon for multiple choice, take 1 hour lunch, then essay questions from 1-5pm. Time yourself, etc. I would recommend getting Volumes 2,3, & 4. Can you pass without them? Yes, but I needed all the help I could get. But for Vol. 1 you get more "bang for you buck." Vols. 2-4 are full building examples, but they certainly helped me out on the exam, and in my work too. I don't have the Hiner book, but I have also heard it is a great resource to have.
  12. I'm not sure when the switch to IBC 2015 occurred, but my guess is it would have been going into last years exams. In the past, on the NCEES website, it would say, "These are the codes for the 2018 exams" meaning there would not be a change in the codes mid-year. It no longer says that. So, it's possible they could do a code update between the April and October exam. I was thinking AASHTO was due for an update, but the changes to the AASHTO code from 7th to 8th edition were significant. So, if a code changes significantly, that may delay the code update as well.
  13. I was able to pass it without a course. I actually think the lateral exam was easier to study for than the vertical exam. You know that 75% of the exam will cover seismic, and about 25% wind. You know to study every section of ASCE 7 seismic chapters, and if you work out every problem in the SEAOC Seismic Design Manual Vol. 1, you will be more than 1/2 way there with seismic study. Other 1/2 of seismic study would be material codes, especially ACI 318 seismic chapter and AISC seismic design manual. Volumes 2, 3, & 4 would also help with this. For wind, studying the ASCE 7 wind chapters and any example problems you can find. ASCE has a wind loads guide that would help. Work out both the NCEES and PPI practice exams, but know that the PPI exam is more in line with the actual exam difficulty. The NCEES exam is too easy, but you may find some similar problems on the actual exam. Do the practice exams just like the exam itself, giving yourself 4 hours for each session. I really didn't use any textbooks while studying or during the exam. Study guides with example problems I think work the best. Also, don't forget that you will have about 10 multiple choice problems concerning bridges. I wrote just the book for you! See attached link. https://www.amazon.com/Bridge-Problems-Structural-Engineering-Exam/dp/1535055464/ref=sr_1_1?s=books&ie=UTF8&qid=1536335590&sr=1-1&keywords=bridge+lateral+loads&dpID=41yQX4vStPL&preST=_SX218_BO1,204,203,200_QL40_&dpSrc=srch
  14. Yep, that is me. Didn't realize my book was being referred to as the "Connor" book. Anyway, I wrote the book specifically for building engineers (such as myself), to help us out on the SE exam bridge questions. I couldn't find any other "good" resources for studying the kind of bridge questions that I saw on the SE exam. There is a chapter in PPI's SERM, and there is also CALTRANS references, but they did not really have the best examples in my opinion. Too involved or did not cover enough subjects. So that's why I wrote the book. The book has 40 vertical and 40 lateral questions. You can order the whole book, or just the books with the vertical or lateral only questions, if you are only taking the lateral or vertical exam. Here is my website with links to the Amazon pages to buy the book - www.davidconnorse.com Obviously, I would prefer that you bought the book, but if the friend who recommended it isn't using it, then maybe you could borrow theirs for the exam. ??
