FE Civil Concrete Design - Design Moment Strength; Φ Mn

[@jferro96]

I have my FE exam in 2 days and your clear explanations are really helping! thanks!

[@Genieprep]

Good luck with your exam, I hope you do well 😊

Your point well taken in regards to “time” it takes to solve this in 3 minutes…especially calculating the PHI value…. Kudos to you

[@Genieprep]

Thank you! I hope you are having luck with your studies. 😊 If you need any help, head over to engenieer.com and start the free MasterClass.

Very Nice explanation of CONCRETE Design problem with solution.Its very easy and point to point. My confidence of solving design problem is increasing by watching your all videos. You are doing great job to share a knowledge with ease. Keep uploading new videos too. Thank you Mam.

I didn't take concrete design in my program (concentrated in transportation), so this is a really helpful and clear explanation. Thank you!

[@Genieprep]

Thank you Mollie for watching. Make sure to subscribe to our website for some free practice problems, www.engenieer.com/all-courses/. Good luck with your studying 😊

Thanks for the great videos. On “d”. I believe you need to take into account the stirrup dia. Rt? So d=24-3-0.5-0.5/2=20.25 in.

If they expect me to do this in three minutes they're nuts.

A video going in depth on simply reinforced beams and two layers of bars solving for PhiM would very helpful.

[@hebfps9682]

I did this problem before watching the video and I used a clear space for the steel of 2.5 inches (it is subjective and this will probably be given to us in the exam to eliminate a wide variety of solutions.) Also, I used my Area of Steel to be 4.40 inches because I include the 1#4 bar. Is this not used? I thought for a stirrup (and maybe this is for shear only) you count the stirrup steel? Great Video. Clear and concise work-through!!

[@Genieprep]

Thank you, I am glad you liked the video. So in the exam, I was given the clear cover, I don't really remember how much 😂. However, I used 3 in for easy calculations and also usually if you are dealing with foundation and the cast against and permanently in contact with ground, minimum of 3" clear cover must be provided (ACI 318-14 page 335). For stirrup, it was just an extra information that we don't really need for this problem, but you are correct, usually stirrups become important when we are mostly dealing with shear. Also keep in mind, that in the exam, you will be given some extra information, that you don't necessarily need, just to throw you off, and that is why it is important to have good understanding of the concepts. I hope this helps 😊

[@Genieprep]

Also, I forgot to mention, great job on doing the problem before watching the video 👏 I am sure if you did mistakes, you will remember them for the test! I try to recommend to do the problems before looking at the solution because that is the best way to learn some thing. I want to thank you for sharing it with us 😊

EXCEPTIONAL FAM!

[@obedondara8629]

Hello, your videos are very helpful thank you!! Did you receive any t-beam, slab or spiral columns problems?

[@him2925]

Thanks for sharing, For some reason I didn’t get any of your new videos

[@joseh7612]

how do you find d though, if they don't give you the length of the smaller side

[@jeremymurphy8151]

From the FE handbook on pg 161, the spacing table has smaller of and then some items. Do you know why sometimes there is an OR and sometimes there isn't?

[@Genieprep]

It does not really matter, if there is OR or no OR, in fact some books, don't use OR and some use AND. The important thing is that you select the smallest spacing for all the provided shear equations. I hope this clarifies your question and good luck.

[@indiojuan1332]

So what is the Mu value? How do we know if phi Mn is satisfied?

[@ingridverastegui170]

Why did you use the same value for d and d subscribe t?

[@daniel083196]

could we also use de (c/d) ratio to determine if phi of .9 was allowed?

[@Genieprep]

Can you please specify what is de? Also, when you use de (c/d), what is the equation equals to? Now what you can use other than the equations provided in this example, is the limits that are shown under the strain conditions graph on page 160, but it will take you longer to figure out the phi value and you still need to calculate for c. I hope this helps and good luck.

[@medoghany6882]

Really I don't HOW to deal with the book of FE CIVIL engineering practice because I heard that it has a lot of information that won't be in the exam also has lack of information that will be in the exam . Please could you give me instructions to learn how to learn all of that information , and another question do you have explained all subjects or there is another subjects?

[@Genieprep]

Are you talking about the FE book by Linderburg? If yes, that is true some of the material is not relevant to the newest FE exam. However, most of the questions are similar to the FE exam questions. So I do recommend it. If you end up using the book and you are not sure if it is relevant to the FE exam, I would suggest that you check the specifications and the reference handbook. If the equation is not provided to you in the reference handbook, then there is high chance you would not get it in your exam. I have not explained all subjects, there are a lot more things to cover. Good luck with your studying.

[@medoghany6882]

Thanks for your answer. We are waiting the best from you .

[@eng763]

hi my dear can send me this book your explain problems thinks

[@Selsius1000]

Are you a professor?
