Great presentation. However, young engineers need to know about the development of the vertical stem bar into the footing! As the bar size gets bigger, the development must be ensured. This may have implications on the footing thickness.

you are pinned to the top of the comments my friend! great point, i mention this at the end of this design example as something we do not cover. #8's will be difficult to fully develop and once I get to that step I would probably reduce my bar size and decrease spacing to help out. very very good point.

@@Kestava_Engineering by using a smaller diameter or Bar, you can also control cracking in case you're designing walls of a water treatment plant to avoid leaking or infiltration.

Thank you, helped me a bunch on my foundation problem.

Kestava, Great video series which has helped me improve my engineering skills. You’ve covered the design of the stem wall but I’m curious to see your approach to designing the reinforcement for the footing!! That would definitely complete the design series

Thank you Kestava for a very helpful video! 😃

Hi Kestava thanks for the awesome content! When you were calculating different iterations was that process a numerical method technique?

Thanks for the video? What does jd mean and where did you come up with 0.875d?

Excellent!

Thank you! Cheers!

Excellent presentation! Try this formula in determining area of steel. As= Mu/4d (Mu in k-ft, d in inches).

Great tip!

Kestava, thanks a lot for the explanation...Can you kindly distinguise for me which of the steels is for Near face and Far face? Also, kindly represent the steels calculated on the retaining wall diagram for me including which direction is for shrinkage reduction

Thanks!

@PhillyBoy thank you! that's amazingly generous and really really appreciate the donation. installing that gold plaque in the auditorium as we speak!

if in the passive segmen we have some pressure, from river water for example, are this include in our Mu calculation for stem calculation? Great presentation btw

absolutely! if you have hydrostatic pressure to account for then it needs to be included in your demand when calculating Mu and Vu

Can you point to where “j” comes from in the ACI 318-14? I’m not too familiar with the code yet

@Kestava_Engineering

its funny - i dont think "j" is really outlined in the ACI - it is a variable that stems from the compression block and coincides with "a" and "c" and is a great tool to estimate beam and rebar sizes without multiple iterations. usually more seasoned engineers use this method as it takes a bit of well rounded understanding on concrete design. but anyone can use it!

Is this better to study for SE1 or SE2

what do you mean by SE1 or SE2?? lemme know!
