I like this learning type of video a lot! I get to learn something very helpful and quick! Prepping for my PE and this is a great way to start my work day!
Great to hear! knocking out a problem every morning before work is exactly what i did when I was studying
I think the use of 4000psi in the question was to ensure that you pick F1 exposure. Since the question describes the exposure as "moderate" there is a choice to be made between F1 ("limited") and F2 ("frequent"). Table 19.3.2.1 indicates that only one of those exposure classes would fit with the criteria for strength. My only issue with the reality of the question is that air content is almost always spec'd as a range, in my experience. Great video!
OMG i didnt pick up on this, but you're absolutely right! F2 requires an f'cmin of 4500 so we know for certain that it was F1. and yes... in the real world Im also used to spec'ing a rang for the entrainment . great comment!
That's a very good point, good catch! Because of that strange choice of words in the question and what it says in Note C of the commentary on page 359 I would have gone conservative with F2 and chosen 5.5%.
Thanks Rich, I'm preparing for the PE and these video are so helpful!
nice! good luck Filipi !
I appreciate your videos, especially as someone no formal structural engineering education. But I'm confused why you continue to reference the ACI code regulation books. The only reference material we are allowed on the exams is the PE civil reference handbook. Those equations and regs are not in there. Are you suggesting we should have these ACI equations and regs memorized for the exam?
Unless im mistaken, you wil also recieve electronic versions of all of the design codes (ACI, NDS, AISC, ASCE, TMS) but check with the NCEES - I may be wrong!
@@Kestava_Engineering You dont get the entire design code. It probably varies by discipline, but for Civil Construction you only get ACI-347R and ACI SP-4 for ACI.
Do you check buckling on shear walls kestava?
you have to check your boundary elements in your shear walls. this is where that would occur
@@Kestava_Engineering how would you do this in a program like etabs which only makes buckling analyses for Columns only and ignores calculation for walls
Hi Rich, My name is Edgar, I´m from México, and I am interesting for the PE Exam, I would like to talk about that with you.
About what? let me know!
looks early!!
