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.
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
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
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
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!
