This 10-minute video explained the important concepts of retaining walls better than my college professor did. Because of that, I don't have a choice but to subscribe to your channel.
Yea that’s what always makes me question college for jobs like this. A contractor building good sized retaining walls can make in a month what a professor makes in a year plus! Lol
Respected Sir , I am very glad to see that still on earth smart person like you exist who have made things easier for students .we all appreciate it from bottom of our heart .
00:05 Retaining walls are structures used to hold earth or any other material, allowing the area above and below it to be usable. 01:30 Different Types of Retaining Walls 02:52 Different types of retaining walls and their failure modes 04:15 The resistance against sliding is mainly provided by the friction between the base slab and the soil below it. 05:31 Active pressure is the pressure actively trying to push the wall along it. 06:51 Design calculations for a granular soil wall are conservative due to the exclusion of certain pressures 08:04 The pressure diagrams for walls under soil and water loads. 09:16 Reinforcement in a cantilever retaining wall Crafted by S_FARH_N
real life on the job illustrations more understood than just a technical approach , nice but really basic without seeing the actual build & placement , passive pressure side of wall is a given & or also deadman or vertical interior wall side placement , looked through but nothing here with that , would change some of the overall material calculations & force formulas obviously...I've worked with retaining wall implemtation as an operator/laborer , loved the concpets & field applications using an engineered study for same
Dang. Great video that saved me from myself in my own plans to build a retaining wall on my property. Thanks for some very helpful info. Now I can build it to never fail. 👍
My concrete foundation is leaning out causing joist to come loose in the center of the house should I create a running concrete base or single concrete footings
Turns out I will not be attempting to DIY my concrete retaining wall after watching this 😅 saved me lots of money and frustration I’m sure. Thanks a million man. Keep these great videos coming!
It saves material. There is no requirement of thicker wall at top hence to reduce cost, the wall can be tapered. Straight walls can be casted if cost is not an issue.
Hi - I summarized your video - a remarkable work. But after New Zealand 7 Richter and 2500 Retaining Walls Collapse - It is important to reinforce a Retaining Wall with Earthquake Resistivity
Hi Zvika, you are correct about considering earthquake forces in design of retaining walls. Many codes around the world now recommend adding the dynamic forces with the static ones.
dear mister @structures explained. I don't mean any offense. but someone else should have spoken. its clear to me that this video is a result of many hours of work (editing, planing, etc). And just to explain my position, i normally have a high understanding with complicated accents (from Argentina, Japan, England, Irland, Australia). but this is bordering unpleasant area. I have to pause and think or read what the person just said, and by doing this i lose focus over the main topic. This is only Constructive Criticism!
Dear sir, Excellent explanations. Do you have Analysis and Design part of Basement Retaining Wall (Step shall be considered as Beam fixed at Base and Pinned at Top.)
You say passive pressure makes the design conservative. Doesn't it help with the stability of the wall in overturning and sliding. Granted it increases the bearing pressure a bit by considering it, but the usual BP of 150Kpa. It should be considered. Also, not considering it makes your design incorrect in the real world when it gets submitted to BC.
Wish I could understand your word's. Would help if you could practice on your English and slowing your word's down with clear syllables. Other than that I think it's a good video, but I will have to read the captions first. Which sucks because it hard to read and watch when your ADHD.
Pls sir gv me ans of this qsn. This question was in my exam of 2 mark... Q: can retaining wall be constructed to retain a siol full of moisture. 10:24 10:24 10:24
I was really having a hard time understanding the passive pressure (and when there is a shear key). I'm always questioning why it is not included in the problems we are solving. That's the problem we are just solving without understanding the principle behind it. Found this video and can't believe that the answer was just to be conservative in the design, that's it. I can't find my courage and time to ask my professor, and I always find videos to understand the concept much deeper but had a hard time finding one. I am really thankful that I found this video. The voice over is clear (but improvements can be made), content is simple and concise. Focuses on principles first to further understand the formulas(it is really helpful for us students) and the figures/animation really solidifies it. You're still 12k+ subscribers but the value you provide is already at a higher level. Please keep making this high quality videos. This "aha" moment just filled me with so much dopamine that I wrote this much. I can't believe it. Peace out.

Where you located sir! Can I hire you? Engineering drawings etc. I have a huge project. Retaining wall - Cantilever wall. I am in USA. Definitely you look like a champion and would be money well spent if you can help me out. Any direct line or number I can send you a message ? Thank you.
Hi, quick question. How do we calculate the shear on the virtual front (excluding base) and shear on front of the base? I believe this is the horizonal component of soil pressure * tan(delta) however, I am unsure how this is then calculated for an undrained case where delta/phi = 0 (as friction is not mobilised) and instead undrained cohesion is used. What would the shear on the front/back be in this case? I assume we would use the cw/c ratio, but is there a part of the formula I am missing? Thanks!
Can you tell about rammed earth construction as compared to concrete? Is compressed stabilised earth block (CSEB) or rammed earth construction durable as compared to concrete or reinforced concrete? Are they a good alternative for creating multi storeyed structure?
