    steel manual

    anyone take the april test find that the new steel manual was difficult to use? i notice that the table for Sx is gone! the standards also list the seismuc design manual as a reference. any questions specifically on this manual?

    new standards

    I took the exam in October and there were questions having to do specifically with masonry design and special inspections. Can someone tell me specifically (which code and page number) where it is written that if special inspections are not performed, the allowable stresses in masonry should be cut in half. I found reference to this in the 1991 version of the UBC. nothing in any recent version of MSJ, or IBC thanks for the help

    any word on the release of RI results??
  4. Wood design... I have the timpber design manual (green one). It is based on the 1997 NDS. Pretty similar. Very good book, but why are the 1997 Fv values almost half of the 2001 Fv values? What changed between those two codes? second question deals with flat use factor Cfu and Size factor CF. If you have a 2x6 being used on the flat (for some reason), you would use the flat use factor when calculating the allowable stresses. What about the shape factor? is the member 2" deep? 6"deep? or is the shape factor not used at all in conjunction with Cfu? thanks

    prestressed concrete

    Not sure how I missed that! thanks for the reply

    Sorry everyone not sure why this was posted three times Wimp

    prestressed concrete

    ACI318 - 05 says max stresses in concrete are as follows... for stresses in concrete immediately after prestress transfer extreme fiber stress in compression = .6f'ci extreme fiber stress in tension = 3 sqrt(f'ci) extreme fiber stress in tension = 6 sqrt(f'ci) for stresses in concrete after losses .45 f'c for compression due to prestress plus sustained load .60 f'c for compression due to prestress plus total load two questions... 1) what does ACI 318-02 say for these values 2) what about the extreme fiber stress in tension for concrete after losses? I don;t see where this is covered in the code. thanks

    need advice

    thanks for the reply! that should really help

    need advice

    On the last April SE-1 exam, I felt like there were a bunch of questions on piles. I didn't know much about them and would like to learn the basics. Can anyone point me to some basic resources on the subject? Also, pre-stressed concrete...without getting into the complexities of the subject, I need to learn the basics as it would pertain to the PE-exam. any resources you can suggest? thanks

    anyone studying yet??

    I am spending quite a bit of time reviewing, but can't help spending a lot of time on the same old stuff! I failed the Strl-1 exam last go around, but did not feel like I was ill prepared. I have been studying for the Oct exam and feel the same feeling.

    Share what you know and ask questions...

    Kevo: How would you rate the License review book that you used (by Alan Williams). Are the questions short and sweet like the exam? Long and drawn out like 246 solved strl problems book? Looking for similar problems to the NCEES strl sample probs book. More of them would be terrific. thanks
  14. I don't know of any allowable value for expansion. I'm not sure where it would say it, but I am sure the code says that the overall design needs to be able to safely handle stress due to expansion/contraction as well as the overall expansion / contraction of concrete should not adversely affect the function of the building or its fixtures. Sorry I couldn't be more helpful. I will look at it in more depth when I review concrete again. Wimp

    anyone studying yet??

    while looking at the topics in this forum I realized that there are not many specific questions about practice problems or questions about subject matter. Is everyone studying yet for the test in October? wimp
